Here is a simple, low tech tip that will work for everyone when looking at developing new laminate colors...
Since we all have leftover sprues/scraps, lay your sprues/scrapes next to other colors to see how they will look. I go through mine all the time and just set colors next to each other for a day or 2 to see if it strikes me. 50% of the time I don't like it, 50% I try the colors in a laminate.
It will also give you an idea if maybe a darker/lighter shade of those colors will vibe together.
I wish the fish would cooperate with this way of thinking!!!!
