Re: link color that meets contrast requirements relative to bg and surrounding text?

Not aware of one tool that does all you need, but I find the Tanaguru contrast finder incredibly useful at being given a failed contrast combination, and suggesting a number of conformant combinations by changing either the foreground background colour accordingly (and automatically).

I guess you could go through the list of compliant colour combinations it suggests with a colour picker to find a combination that meets your requirements for foregroundbackground, AND textlink text colours.

Of course, underlining links is desirable, but would they settle for bolding them instead if underlining is not an option? This would also satisfy the requirement.

Cheers
Joe
