I've just read the chapter on color. In comparison to another class I'm taking... Color.... it's interesting. Colors are extremely complex and very subjective. Colors schemes really do need to appeal to the target audience and we might not agree on what colors are appropriate... Reading the chapter was very similar to my most recent lecture... Red is this and blue is that but don't think about it too much because it's different for everyone. The traditional color wheel (first drawn out by Newton in the 17th century, though I was sad that Da Vinci wasn't mentioned...) is the best starting tool, and it's always best to try different color combinations out for yourself. There is no mistake better than the one you make yourself.
