A light, minimal plotting theme with soft coastal colors and serif (or sans) typography. Available for both matplotlib/seaborn and plotly.

Interactive version

pip install tidepool-theme

Or with specific backends only:

pip install "tidepool-theme[mpl]"
pip install "tidepool-theme[plotly]"
pip install "tidepool-theme[all]"

import tidepool
tidepool.set_mpl_style()

# seaborn inherits the style automatically
import seaborn as sns
sns.scatterplot(...)

Pass font="sans" for Inter instead of the default Source Serif 4.

Note: calling sns.set_theme() after set_mpl_style() will override the style. Use seaborn plotting functions directly instead.

import tidepool
tidepool.set_plotly_template()

import plotly.express as px
fig = px.scatter(...)  # uses tidepool template by default

Pass font="sans" for Inter instead of the default Source Serif Pro.

• Background: #fafafa — light warm gray
• Fonts: Source Serif 4 (default) and Inter (opt-in via font="sans"), both bundled under SIL Open Font License. Plotly uses Source Serif Pro / Inter via Google Fonts / system fallback.
• Color cycle: 34 soft coastal tones starting with lightseagreen, lightsalmon, steelblue
• Colormaps: purpor / purpor_r (sequential) and tealrose / tealrose_r (diverging), from CARTOColors
• Layout: no grid, left+bottom spines only, clean axis lines
