Hi David,
To answer your question about ending the contest, I think we should try to finalize the colors at the least before you close it. Let me see what I can do with the photos you posted, and I have another idea about communicating on colors that will help make this a bit easier, I think. As opposed to sending images, maybe you could try looking at color swatches and color schemes online.
I love the the colourlovers website for this purpose.
Here are single colors:

http://www.colourlovers.com/palettesI'll go look at it myself right now and find a few palettes that I think might be up your alley.
Also, I'll try using some Pantone spot colors in the design instead of process colors. These are premixed inks that tend to be a little brighter than CMYK.
I understand what you mean about pop, but you'll be hard-pressed to find a color that people will feel like they've never seen before. I don't mean to burst your bubble here, but everyone sees color a little differently, and I worry that an expectation like that will make finding the perfect color an impossible feat! I think the real key is finding the right two colors so that the color of the single pixel seems unexpected, rather than completely new.
Also, just so you know, I have a full-time job that I go to during the day, which is why I'm only active here in the evenings (eastern time). So when long periods go by without a word from me, it's because I'm working for the man designing web applications! :)
