Inline Color Swatch

Inline Color Swatches shows a small color preview next to supported CSS color values written in inline code spans.

This plugin follows GitHub Flavored Markdown behavior:

• ✅ Inline code spans (`...`) are supported
• ❌ Code blocks (```...```) are intentionally excluded

Supported formats

• Hex: #RRGGBB, #RGB, #RRGGBBAA, #RGBA
• RGB(A): rgb(R,G,B), rgb(R,G,B,A) (case-insensitive)
• HSL(A): hsl(H,S,L), hsl(H,S,L,A) (case-insensitive)

[!note]

• Uppercase and lowercase letters are not distinguished.
• Supported color models cannot use any characters that contain leading or trailing whitespace within backquotes.
