(Catppuccin) Incorrect Base16/24 mapping for Catppuccin themes

[tummetott]

Hello,

This is a issue duplicate of: tinted-theming/tinted-nvim#30

According to the Base24 specification:

Dark Theme: Colors from base00 to base07 should range from dark to light.

This is the current colors:

base01 is darker as base00 which is probably wrong. You can see this in the catppuccin spec:

Another issue: Catppuccin defines eight distinct steps between base (background) and text (foreground), while Base24 only allows four intermediate steps. The current mapping ends up being skewed toward darker tones.

I would suggest the following mapping instead:

base00 = base          # background
base01 = surface0
base02 = surface2
base03 = overlay1
base04 = subtext0
base05 = text           # foreground

This mapping preserves a monotonic dark to light progression and distributes the available contrast more evenly, while still respecting the Base24 specification.

I used catppuccin-frappe as an example, but the same issue appears in all other Catppuccin variants as well.

This issue affects base16 and base24

Thank you
