I have chosen teal for this entry. It is a popular color this season, and I have seen it used for many items of clothing; it is also one of my favorites. Let me know what colors you think would be fantastic.
You can see a mock up of a couple of shoe styles using other color combinations in my photostream at Flickr. There is also a picture with samples of just a few of the possible combinations that can be done. Links for those are in the comments below and the thumbnails above. If they appear to be missing just click on the "?" and you will be taken to my photostream.
I would probably go smaller than this for shoes, but you can't see the design if I make it smaller here.
