Noctalia shell's builtin "Catppuccin" palette is Mocha, not your catppuccin/nix flavor

Setting [theme] source = "builtin" and builtin = "Catppuccin" in noctalia's theme.toml gives Catppuccin **Mocha**: in src/theme/builtin_palettes.cpp, surface is #1e1e2e and error is #f38ba8. If the rest of the system uses catppuccin/nix with flavor = "macchiato" (surface #24273a, red #ed8796), the bar is a shade darker and its red is different.

For a matching flavor, put a palette JSON in ~/.config/noctalia/palettes/<Name>.json and set source = "custom" and custom_palette = "<Name>". A missing or invalid file silently falls back to the Noctalia builtin.

The session/power widget is filled with the error role (capsule_fill = "error"). Under any Catppuccin flavor that is the pastel red, which reads as pink. Catppuccin has no saturated red (maroon is similarly pink), so a true red means overriding that one role.
