Hi, col=552 isn't the same as colors()[552] - I think the former is drawn from your current palette, with recycling of indices. The default color palette has only eight colors.
You need instead col=colors()[552] It's very difficult to get 20-30 readily distinguishable colors. You might try the RColorBrewer package for smaller tasks, though.
