Color selection for foreground and background
Users can freely select both the background color and the text/icon color. The selection is made using a color selection field that supports various formats, including:
- HEX
- RGB
- HSL
Alternatively, a color code can be entered directly or selected using the color picker.
Direct preview
A preview is displayed on the right-hand side, showing the selected background together with text and icons. Sample texts in regular and large fonts as well as icons help to realistically assess the effect of the color combination.
Contrast ratio calculation
The tool automatically calculates the contrast ratio between the foreground and background colors. This is displayed numerically – the higher the value, the clearer the contrast.
Compliance indicator for different use cases
The result is broken down into three categories:
- Regular text
- Large text
- Icons / UI elements
