Dev notes: colors and font

Colors and font

Here are some notes about changing author colors and the font used across the app.

Colors

In Python

• Colors are currently set in the Python script, using two Seaborn palettes ("bright" and "dark") in sequence.
• The block afterwards can be uncommented to set the colors manually, though note that there must be at least 12 colors (since that's the number of authors).
• These colors must be in the format [r, g, b, a] where each is a value from 0 to 255.
• The colors here will be added to the JSON-LD Person records (authors.json) outputted from the Python script.

In JavaScript

• Colors are currently accessed by pulling the color value from each JSON-LD Person record.
• They are used for arcs in the Itineraries layer and names in the authors list.
• Both of those could be overridden, though it is recommended to then edit the Python script to remove the color field from the JSON-LD data, so that there is no mismatch between the data and the frontend.

Font

• The font DM Sans is used across the site currently. It is inherited from Peripleo.
• To change, set the font in the following places:
  • html, body, #app CSS block
  • Month range input
