"Overrides for `modus-vivendi-tritanopia-palette'.
Mirror the elements of the aforementioned palette, overriding
their value.
For overrides that are shared across all of the Modus themes,
refer to `modus-themes-common-palette-overrides'.
Theme-specific overrides take precedence over shared overrides.
The idea of common overrides is to change semantic color
mappings, such as to make the cursor red. Wherea theme-specific
overrides can also be used to change the value of a named color,
such as what hexadecimal RGB value the red-warmer symbol
represents."
