Since I'm colourblind -- I can't see the pretty numbers in those colour perception tests -- I've really enjoyed this analysis by Geri Coady of 24 WAYS as she explains how to build websites and apps that are colour accessible.
One of the most common annoyances I've heard from people who are colour-blind is that they often have difficulty purchasing clothing and they will sometimes need to ask another person for a second opinion on what the colour of the clothing might actually be. While it's easier to shop online than in a physical store, there are still accessibility issues to consider on shopping websites.
Let's say you've got a website that sells T-shirts. If you only show a photo of the shirt, it may be impossible for a person to tell what colour the shirt really is. For clarification, be sure to reference the name of the colour in the description of the product.
