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
