### Problem
People with a low eye-sight need a minimum contrast between text and background. In some parts of the application the current contrast ratio is 1,7:1 which is below the threshold of 3:1. Because of that some users cannot read the content.
This happens for example when a button is disabled (e.g. hide filter section or stop watching a work package).
### Recommendation
- Between text and background should be a minimum contrast ratio of 3:1 for large fonts and 4,5:1 for smaller fonts.
- While increasing the contrast make sure that the button can still be seen as “disabled”. In the worst case make change the color only in accessibility mode.
- To check the contrast ratio analysis programs like the „Colour Contrast Analyzer“ of the „Web Accessibility Toolbar“ (IE) can be used.
