bash

cat policyengine-app/src/style/colors.js

Plotly Chart Formatting

Standard PolicyEngine chart:

python

import plotly.graph_objects as go

def format_fig(fig):
    """Format chart with PolicyEngine branding."""
    fig.update_layout(
        # Typography
        font=dict(
            family="Roboto Serif",
            color="black"
        ),

        # Background
        plot_bgcolor="white",
        template="plotly_white",

        # Margins (leave room for logo)
        margin=dict(
            l=50,
            r=100,
            t=50,
            b=120,
            pad=4
        ),

        # Chart size
        height=600,
        width=800,
    )

    # Add PolicyEngine logo (bottom right)
    fig.add_layout_image(
        dict(
            source="https://raw.githubusercontent.com/PolicyEngine/policyengine-app-v2/main/app/public/assets/logos/policyengine/teal.png",
            xref="paper",
            yref="paper",
            x=1.0,
            y=-0.10,
            sizex=0.10,
            sizey=0.10,
            xanchor="right",
            yanchor="bottom"
        )
    )

    # Clean modebar
    fig.update_layout(
        modebar=dict(
            bgcolor="rgba(0,0,0,0)",
            color="rgba(0,0,0,0)"
        )
    )

    return fig

# Usage
fig = go.Figure()
fig.add_trace(go.Scatter(x=x_data, y=y_data, line=dict(color=TEAL_ACCENT)))
fig = format_fig(fig)

Current implementation:

bash

# See format_fig in action
cat givecalc/ui/visualization.py
cat policyengine-app/src/pages/policy/output/...

Blog Post Charts (Standalone HTML)

When creating standalone Plotly HTML files for blog posts, use these specific settings:

Font: Use "Roboto" (not "Roboto Serif") with Google Fonts embed:

python

FONT_FAMILY = "Roboto, Arial, sans-serif"

# After generating HTML, embed font
html = fig.to_html(include_plotlyjs='cdn')
html_with_font = html.replace('</head>',
    '<link href="https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700&display=swap" rel="stylesheet"></head>')
with open('chart.html', 'w') as f:
    f.write(html_with_font)

Background: LIGHT_GRAY (#F2F2F2) for better blog integration:

python

fig.update_layout(
    plot_bgcolor="#F2F2F2",
    paper_bgcolor="#F2F2F2"
)

Logo positioning: x=0.95, y=-0.2 avoids cutoff:

python

images=[{
    "source": "https://raw.githubusercontent.com/PolicyEngine/policyengine-app-v2/main/app/public/assets/logos/policyengine/teal.png",
    "xref": "paper", "yref": "paper",
    "x": 0.95,  # Not 1.0 - prevents cutoff
    "y": -0.2,
    "sizex": 0.15, "sizey": 0.15,
    "xanchor": "right", "yanchor": "bottom"
}]

Margins: Increase right margin when x-axis extends to boundary:

python

# For charts showing $0-$2B or similar
margin=dict(t=120, b=120, l=120, r=80)  # r=80 ensures last tick visible

Grid and axes:

python

xaxis=dict(
    gridcolor="#FFFFFF",      # White grid on LIGHT_GRAY background
    zerolinecolor="#FFFFFF",
    tickformat='$,.1f',       # Units in tick labels
    ticksuffix='B'            # Not in axis title
),
yaxis=dict(
    gridcolor="#FFFFFF",
    zerolinecolor="#FFFFFF",
    ticksuffix='%'
)

Colors for reference lines: Use GRAY (#808080), not red:

python

# Reference/statutory lines
line=dict(color="#808080", width=2, dash='dash')

Stepwise patterns: Use 10,000+ points for discrete boundaries:

python

# For charts showing $2M increments
wealth = np.linspace(0, 2.0, 10000)  # Fine granularity
line=dict(shape='hv')  # Horizontal-vertical steps

Legend: Position inside chart when needed:

python

legend=dict(yanchor="top", y=0.99, xanchor="left", x=0.01)
# Or remove entirely if obvious: showlegend=False

Chart Colors

For line charts:

Primary line: Teal (#39C6C0) or Blue (#2C6496)
Background lines: Light gray (rgb(180, 180, 180))
Markers: Teal with 70% opacity

For bar charts:

Positive values: Teal (#39C6C0)
Negative values: Dark red (#b50d0d)
Neutral: Gray

For multiple series: Use variations of blue and teal, or discrete color scale:

python

colors = ["#2C6496", "#39C6C0", "#17354F", "#227773"]

Typography

Charts:

python

font=dict(family="Roboto Serif", size=14, color="black")

Axis labels:

python

xaxis=dict(
    title=dict(text="Label", font=dict(size=14)),
    tickfont=dict(size=12)
)

Load Roboto font:

python

# In Streamlit apps
st.markdown("""

Color Definitions

⚠️ IMPORTANT: App V2 Transition

PolicyEngine is transitioning to policyengine-app-v2 with updated design tokens. Use app-v2 colors for new projects.

Current colors (policyengine-app-v2):

typescript

// policyengine-app-v2/app/src/designTokens/colors.ts

// Primary (teal) - 50 to 900 scale
primary[500]: "#319795"  // Main teal
primary[400]: "#38B2AC"  // Lighter teal
primary[600]: "#2C7A7B"  // Darker teal

// Blue scale
blue[700]: "#026AA2"     // Primary blue
blue[500]: "#0EA5E9"     // Lighter blue

// Gray scale
gray[700]: "#344054"     // Dark text
gray[100]: "#F2F4F7"     // Light backgrounds

// Semantic
success: "#22C55E"
warning: "#FEC601"
error: "#EF4444"

// Background
background.primary: "#FFFFFF"
background.secondary: "#F5F9FF"

// Text
text.primary: "#000000"
text.secondary: "#5A5A5A"

To see current design tokens:

bash

cat policyengine-app-v2/app/src/designTokens/colors.ts
cat policyengine-app-v2/app/src/styles/colors.ts  # Mantine integration

Legacy colors (policyengine-app - still used in some projects):

javascript

// policyengine-app/src/style/colors.js
TEAL_ACCENT = "#39C6C0"  // Old teal (slightly different from v2)
BLUE = "#2C6496"         // Old blue
DARK_GRAY = "#616161"    // Old dark gray

To see legacy colors:

bash

cat policyengine-app/src/style/colors.js

Usage in React (app-v2):

typescript

import { colors } from 'designTokens';

<Button style={{ backgroundColor: colors.primary[500] }} />
<Text style={{ color: colors.text.primary }} />

Usage in Python/Plotly (use legacy colors for now):

python

# For charts, continue using legacy colors until officially migrated
TEAL_ACCENT = "#39C6C0"  # From original app
BLUE_PRIMARY = "#2C6496"  # From original app

# Or use app-v2 colors
TEAL_PRIMARY = "#319795"  # From app-v2
BLUE_PRIMARY_V2 = "#026AA2"  # From app-v2

Typography

Fonts:

For charts (Plotly):

python

font=dict(family="Roboto Serif")

Streamlit Theme Configuration

Standard .streamlit/config.toml:

toml

[theme]
base = "light"
primaryColor = "#39C6C0"              # Teal accent
backgroundColor = "#FFFFFF"            # White
secondaryBackgroundColor = "#F7FDFC"  # Teal light
textColor = "#616161"                  # Dark gray
font = "sans serif"

[client]
toolbarMode = "minimal"
showErrorDetails = true

Usage:

bash

# Create .streamlit directory in your project
mkdir .streamlit

# Copy configuration
cat > .streamlit/config.toml << 'EOF'
[theme]
base = "light"
primaryColor = "#39C6C0"
backgroundColor = "#FFFFFF"
secondaryBackgroundColor = "#F7FDFC"
textColor = "#616161"
font = "sans serif"
EOF

Current examples:

bash

cat givecalc/.streamlit/config.toml

Design Patterns by Project Type

Streamlit Calculators (GiveCalc, SALT Calculator, etc.)

Required branding:

✅ .streamlit/config.toml with PolicyEngine theme
✅ Charts use format_fig() function with logo
✅ Teal accent color for interactive elements
✅ Roboto Serif for charts

Example:

python

import streamlit as st
import plotly.graph_objects as go

# Constants
TEAL_ACCENT = "#39C6C0"

# Streamlit UI
st.title("Calculator Name")  # Uses theme colors automatically
st.button("Calculate", type="primary")  # Teal accent from theme

# Charts
fig = go.Figure()
fig.add_trace(go.Scatter(x=x, y=y, line=dict(color=TEAL_ACCENT)))
fig = format_fig(fig)  # Add branding
st.plotly_chart(fig)

Jupyter Notebooks / Analysis Scripts

Required branding:

✅ Charts use format_fig() with logo
✅ PolicyEngine color palette
✅ Roboto Serif font

Example:

python

import plotly.graph_objects as go

TEAL_ACCENT = "#39C6C0"
BLUE_PRIMARY = "#2C6496"

fig = go.Figure()
fig.add_trace(go.Scatter(
    x=data.income,
    y=data.tax_change,
    line=dict(color=TEAL_ACCENT, width=3)
))

fig.update_layout(
    font=dict(family="Roboto Serif", size=14),
    title="Tax impact by income",
    xaxis_title="Income",
    yaxis_title="Tax change ($)",
    plot_bgcolor="white"
)

# Add logo
fig.add_layout_image(...)

React App Components

Color usage:

javascript

import colors from "style/colors";

// Interactive elements
<Button style={{ backgroundColor: colors.TEAL_ACCENT }}>
  Click me
</Button>

// Links
<a style={{ color: colors.BLUE }}>Learn more</a>

// Text
<p style={{ color: colors.DARK_GRAY }}>Description</p>

Current colors:

bash

cat policyengine-app/src/style/colors.js

Visual Guidelines

Chart Design Principles

Minimal decoration - Let data speak
White backgrounds - Clean, print-friendly
Clear axis labels - Always include units
Formatted numbers - Currency ($), percentages (%), etc.
Logo inclusion - Bottom right, never intrusive
Consistent sizing - 800x600 standard
Roboto Serif - Professional, readable font

Color Usage Rules

Primary actions:

Use TEAL_ACCENT (#39C6C0)
Buttons, highlights, current selection

Chart lines:

Primary data: TEAL_ACCENT or BLUE_PRIMARY
Secondary data: BLUE_LIGHT or GRAY
Negative values: DARK_RED (#b50d0d)

Backgrounds:

Main: WHITE (#FFFFFF)
Secondary: TEAL_LIGHT (#F7FDFC) or BLUE_98 (#F7FAFD)
Plot area: WHITE

Text:

Primary: BLACK (#000000)
Secondary: DARK_GRAY (#616161)
Muted: GRAY (#808080)

Accessibility

Color contrast requirements:

Text on background: 4.5:1 minimum (WCAG AA)
DARK_GRAY on WHITE: ✅ Passes
TEAL_ACCENT on WHITE: ✅ Passes for large text
Use sufficient line weights for visibility

Don't rely on color alone:

Use patterns or labels for different data series
Ensure charts work in grayscale

Common Branding Tasks

Task 1: Create Branded Plotly Chart

Define colors:

python

TEAL_ACCENT = "#39C6C0"
BLUE_PRIMARY = "#2C6496"

Create chart:

python

fig = go.Figure()
fig.add_trace(go.Scatter(x=x, y=y, line=dict(color=TEAL_ACCENT)))

Apply branding:

python

fig = format_fig(fig)  # See implementation above

Task 2: Setup Streamlit Branding

Create config directory:
bash
```
mkdir .streamlit
```

Copy theme config:

bash

cat givecalc/.streamlit/config.toml > .streamlit/config.toml

Verify in app:

python

import streamlit as st

st.button("Test", type="primary")  # Should be teal

Task 3: Brand Consistency Check

Checklist:

Charts use Roboto Serif font
Primary color is TEAL_ACCENT (#39C6C0)
Secondary color is BLUE_PRIMARY (#2C6496)
White backgrounds
Logo in charts (bottom right)
Currency formatted with $ and commas
Percentages formatted with %
Streamlit config.toml uses PolicyEngine theme

Reference Implementations

Excellent Examples

Streamlit calculators:

bash

# GiveCalc - Complete example
cat givecalc/ui/visualization.py
cat givecalc/.streamlit/config.toml

# Other calculators
ls salt-amt-calculator/
ls ctc-calculator/

Blog post charts:

bash

# Analysis with branded charts
cat policyengine-app/src/posts/articles/harris-eitc.md
cat policyengine-app/src/posts/articles/montana-tax-cuts-2026.md

React app components:

bash

# Charts in app
cat policyengine-app/src/pages/policy/output/DistributionalImpact.jsx

Don't Use These

❌ Wrong colors:

python

# Don't use random colors
color = "#FF5733"
color = "red"
color = "green"

❌ Wrong fonts:

python

# Don't use other fonts for charts
font = dict(family="Arial")
font = dict(family="Times New Roman")

❌ Missing logo:

python

# Don't skip the logo in charts for publication
# All published charts should include PolicyEngine logo
