Palette (background colors)

The 16-color palette of each theme — the colors native tags like <red> / <RED> map to:

dracula palette

nord palette

catppuccin palette

monokai palette

dark palette

light palette

Listing themes

from loguru_themes import list_themes

list_themes()
# ['catppuccin', 'dark', 'dracula', 'light', 'monokai', 'nord']

Names are case-insensitive ("Dracula" works). An unknown name raises a KeyError listing the available names.

Getting a theme object

from loguru_themes import get_theme

theme = get_theme("dracula")
theme.levels["INFO"].color   # '#bd93f9'
theme.accent, theme.dim, theme.fg

Useful when you want to inspect or customize a theme, or reference its colors in your own format.

Highlights

ERROR renders the message text in red (like the standard logging look).
CRITICAL renders the message bold on a red background to stand out.

Both are configurable per level — see Customizing.

Light vs dark

dark/light are tuned for dark/light terminal backgrounds respectively; dracula, nord, catppuccin, and monokai are dark-background palettes.
