I really like the colours of the syntax highlighting in Apple’s XCode, I apply the colouring to all of the other code editing applications I use, these being Netbeans and BBEdit. For the 3.2.x versions there are only some small changes in the colours. With the advent of OS 10.6 Snow Leopard we get Apple’s new Menlo font which is very nice. Colour values were taken from XCode 3.2.3.
