JohnOne, you are technically correct in that one color on top of whatever we are stitching onto would be considered a one color design. But we can accept a 2-color design, we seem to have a mix of one and two color submissions here, and a few 3-color. It is OK to consider two colors into this design in addition to whatever it will be stitched onto. But be mindful that the stitched design will have to be placed onto a white jersey as well as a darker jersey, still looking like a dark burgundy (dark purple/red) color. In that respect, it's probably best to keep the design as self-contained as possible. Also speaking of self-contained, the logo will be produced as a patch and then applied to the jerseys. so the amount of intricate details that are allowed to show-through or left as void space in the patch is somewhat restricted.
Also gradients are not possible, but as some have used hatching and other shading effects, that is fine.
The current 1st and 2nd place ranked designs would both be considered 2-color designs in this situation, because if created as a twill patch, in the bottle cap shape, it would consist of both the black and the white, or whatever two colors we ultimately choose. Same with the 3rd-ranked submission. The 4th-ranked is technically a 3-color.
We're still undecided, but are considering the logo to be stitched as silver and black, so black and white submissions are just fine. And for better visual effect, it wouldn't hurt to place them onto a dark burgundy colored background.
I'm sorry if I haven't been clear on this point up until now.
