skin tone help

I am working on something and I need help with a skin tone. The character is a combination of my Venusian Vigilante I done based off of Hyperman's work, Gem, and Martian Manhunter. Now I don't want to use green or blue because they are those skin colors and I'm trying to stay away from red because that's Gem's skin color. The eyes I am doing an light blueish color. If you can help that will be great. Thank you.

leaves you with yellow, orange (redish but not red) and purple as main colours...

The suit is colored white/silver with purple trim. I might have to go with green if the others don't work, I'm leaning towards yellow.

Here is what I have so far.

I think if your main concern is how the skin tone wll look in combination with the colours of the costue the best idea would be to finish the micro and then try out diffrent skin tones... or post the nearly finished micro and then people can give better tips how the skin colours could/should look
