Hi Kieron (and all)
Yes, this is the site: www.vischeck.com. I find it useful for teaching
people about colour blindness, as until you see pictures (such as the
'how many fruits can you see' one, it's difficult to 'get' what the
problem is), as well as for specifically teaching about accessible web
design.
Another thought I've had ... I think it can help improve intellectual
access if the colours chosen 'echo' the colours of fabrics involved
(this is for on-site interpretation, whether the plan/elevation is in a
guide book, or on fixed panels) - or at least, not contradict them.
With best wishes,
Pat
