I found this fantastic tool to test the contrast between colours used on a website
http://juicystudio.com/services/colourcontrast.php#contrast
I have been relying on this tool and using the findings to form a base for my arguments in accessibility audits that I have carried out.
What struck me is that I haven’t really invested any time in deciding whether I trust these findings or not. They have placed the W3C recommendations as a guide about acceptable tolerances of colours:
((Red value X 299) + (Green value X 587) + (Blue value X 114)) / 1000
This really doesn’t mean much to me. I haven’t taken the time to understand what this means or in fact read it in any detail, I have just taken it as fact that the tool is using this algorithm and is producing accurate results for me.
So what has made me trust this?
- a word of mouth recommendation; and
- its reference to the W3C
What makes me use it and keep on using it?
- the subconscious trust I have as a result of the above; and
- it gives me results, fast
