Today I found two links I would like to share with you:
The first one is from Chris, the writer behind Mixing Memory. He had a closer look at the Color Opponency in Synaesthesia. People with Synaesthesia perceive colors even when looking at black letters and numbers. Some researchers discovered now, that if you show such persons wrongly colored color-names (e.g. red) they have very different reaction times than people with no Synaesthesia.
The second link is for web publishers. Skye claims that you have to Check Your Link Colors – You May Need to Redecorate! This is not only true for professional web designers but also for any blogger running a free blog software. If you are interested in accessibility you might enjoy her weblog about all access blogging .
