Re: Minimal style needed to make links accessible?

There is a also very nice contrast analyzer available on the Paciello
group's site
also linked from the Web Accessibility Tools Consortium page

You can select any two colors from a page using the eye-dropper tool.
The fields are labeled Foreground and Background, but if you select one
text color as the foreground, and the other text color as the
background, you will get the contrast ratio between the two text colors.

You can use this tool to test contrast in any application, not just for
content viewed in a Web browser. For example, you could test the text
contrast in a PDF document or any software dialog also.

As an aside, the Juicy Studio toolbar is great, but I have not figured
out how to get it to test contrast for text that is found on top of a
background image. It seems to test only colors specified as text and
background colors in the CSS.

Hi Friends,
Jared Smith has given great explanation on Distinguishable links.
Well, As an Accessibility tester how can we predict the Contrast between
link text and non- text.
Is there any Tool to predict that? Generally i use Juicy Studio
analyzer, but it Predicts contrast of text and back ground. Any help is
