Why colour contrast is important
The crux of it is readability.
- High contrast allows everyone to read text at greater speed.
- As contrast sensitivity declines with age, older people require more.
- Old washed-out monitors have very poor contrast.
- High contrast helps combat screen glare on mobiles.
With good colour contrast you reach more users!

So another colour contrast test tool?
On the day-to-day I required a simple tool which would give me the nearest AA match to a colour pair. It appeared the other tools only resulted in a pass or fail.
This tool allows me to quickly bounce back to the designers a colour which passes, allowing them to make an informed decision over appropriateness.
That and it makes for a handy Hex to RGB converter. Actually it'll convert colour keywords, HSL, HSLa or RGB into either Hex or RGB.
A third of your visitors need glasses
In fact some two-thirds of your audience need help to view websites. Amazingly, half of them don't wear their glasses or contacts when browsing online.
Please bear this in mind when choosing colour combinations. Remember, poor colour contrast and font size choices, may make text too difficult to read.
