In the Web Design & Development and Information Design courses that I teach we often talk about colour-blindness, as it is one (of many) accessibility concerns that designers should consider. To help students see how their work online may be affected, I put together some colour-blindness bookmarklets to help students quickly check their websites.
What is a bookmarklet?
Why a bookmarklet?
I have tried building out other full-webpage tools in the past. A tool where students can load up their website and flip through it entirely within the tool.

As a result, bookmarklets allow students to quickly apply the filter to each page within their own browser, without having to set lax security permissions on their web space.
