This tool analyzes the contrast between foreground and background colors using WCAG and APCA models.
Colors may be:
- Entered directly as individual CSS values.
- Evaluated and interactively adjusted using HSL or OKLCH sliders.
On wider displays, colors may also be:
- Entered as a CSS snippet with multiple (up to 28) variables using the CSS Color Palette.
- Moved (dragged) between the palette, a drag-and-drop area, a color scheme builder, and the foreground and background panels.
Supports the Display P3 color space.
This tool is for those who need precise, standards-aware contrast feedback while working in modern CSS color workflows.
