Search engines and humans are always looking for relevance. When we first open a document on the web (or in our mail), one of our first actions is frequently to determine whether this document is relevant to our needs.

I’ve always believed that web site accessibility depends on an understanding of accessibility issues — not on technical issues.

Some decisions are fundamentally technical, but a huge part of web site accessibility is purely visible — and just understanding accessibility issues will make a huge difference. To that end, here are a few quick comments about color blindness. Color blindness (or color perception […]
