Hmmm. That's an interesting idea.
Now...how do we want to go with this? Should males have the bright colors and females be brown or drab? Probably not, since their predators and not prey. I might let them be brightly colored, even though I doubt they would be from an evolutionary standpoint.
Other question is whether or not the females should be larger than the males.
In modding progress news, I've run into some odd bugs that I'm trying to work out. For some reason some reactions are giving me the results I expect and others are giving me 150x what I expect. I just had a test fort produce 150 Void Crystal Bars from a single reaction last night. Nice, I suppose, since the only metal on site is Tetrahedrite. But not exactly what I was going for. So I'm trying to figure out what is going on there.
Also, you may notice that world-gen populations are a bit wonky. The various carnivorous races, like the Dyansauri, had to be set to [NO_EAT] to keep them from all starving by year 4. So now they regularly get empires with over 100K citizens while everyone else is lucky to have 10k. Shouldn't effect Fortress mode too much, but it might make Adventure mode a bit wonky.
I might need to make an Adventure Mode friendly version with some tweaks to it.
