Field Guide currently in the works! In order to get more involvement in the Field Guide, I'd like to have (potential, at this point) RP members suggest subtypes for the RP via PM. The aforementioned reason for dinosaurs being colored the way they are is based in part on various skins from Primal Carnage. The Blue Jewel Oviraptor, for example:

[quote]Sometimes what you think is a good idea in your head turns out to be a pretty stupid idea when you actually put it into practice. Making a completely black feathered dinosaur for the purposes of invisible stealth purposes seemed like a good idea when it was first conceived, however when they disappeared from sight during every field test, they were unable to be accurately assessed and a week had to be spent finding them again each time it was decided that for practicality purposes they simply couldn’t be black. 
To this end the lab boys were ordered to “get back in there and paint it blue or something so we can see the blasted things”. And so they did, and thus the ultimate night time stealth dinosaur was decorated in a bright and vibrant blue pattern so that their stealth abilities could be accurately assessed. 
The tests didn't go well.[/quote]

The text descriptions most likely won't be as humorous, but can be used to explain an animal's appearance (version number, "can't-see-the-damn-thing", etc.). If you run across a coloration you would like to see, submit it! It might just be added to the Field Guide!
