Catppuccin color theme accent change (or custom accents) #76

Witchshy has Catppuccin as a color theme option which does correctly match Catppuccin's "base" color for background usage but the accent color doesn't match any color on the pallet on dim (Macchiato), dark (Mocha), or light (Latte)

It would be neat if the accent color was changed to one from the pallet to fit with the background (preferably Mauve as it's still a purple color and also my personal choice of accent) but custom accents (or even full custom themes) would also be cool

(hell even if the existing hue slider was able to be split between the accent and background separately)
