I think that’s a great idea.
Personally, I think the best colors for mass production are the more vivid ones, but you should do at least one “natural” one in browns and creams and tans and such, and I think one in white, or white and silver, that one in the pizza pic is really lovely! But I’ve noticed the ones I like best have metallics in, and this seems to be a bit of a theme with other people’s tastes too.
Edit – I had an idea. Except I think there are too many… But I could go through and number the different colored poads on the pizza picture, and then make a poll so people could vote for the number of the onethey like. But polls only have something like ten options here, and there are more than that.
