In light of your OGR feedback and Photoshop classes, many of you have been encouraged to think much more creatively about the use of colour in terms of your 'concept art for animation'. Animation loves expressive, expressionistic colour schemes, but putting effective combinations together can be a bit daunting. However, if you want to accomplish worlds as rich and ravishing as the examples feature below, you should make use of this very useful Online Colour Scheme Designer - from which you can export colour swatches into Photoshop ready-to-use. Just follow the export instructions on the original post and get stuck in. It's high time you committed to colour. I want to see some colour wheel fireworks! Have fun!
