If you know what a pixel is, you can generally fiddle around with the layout maker until you get what you want. You don't actually need to know colour codes or anything like that, since you can pick them from a list. Or at least, that's what I do. :]
I think there are a few layout threads on the forums too, in case you'd like to browse.
