Color Contrast Analyser
An Alternative Analyser
- Why 'alternative'?
- Because I believe that the standard analysers that apply the World Wide Web Consortium (W3C) thresholds place too much emphasis on high contrasts.
- Why is high contrast a problem?
- It can make pages difficult to read for those with some forms of dyslexia and it causes text pixelation for visually-impaired users of screen magnifiers.
- So, what's different about this analyser?
- As well as using the W3C thresholds, it uses the Hewlett Packard Color Difference threshold which, at 400, is 20% lower than the corresponding W3C figure. It also provides a 'high contrast' warning if the colour difference exceeds 600
