I like the simplicity of both these colourways; three colours, with a slowly changing striping pattern to keep things interesting.
To enter, just leave a comment and let us know what three colours you would pick for your own version of this striping pattern. I will randomly select a winning comment at noon PST on Saturday Sept 14. (I was going to say Friday, but realised that will be Friday the 13th. I'm not particularly superstitious, but still. Not the ideal date for a celebratory game of chance.)
