I agree, there is not much info on gecko color change, I assumed, based on observations on my specimens, that the melanophores control most of the color change in ciliatus, merely because even my bright red female (who has little noticeable black) only gets more and less intense, which would suggest the change in "darkness" suggestiung melanophores. She does not become 'more' or 'less' red but merely varies in intensity. I just had a conversation with Dr. Aaron Bauer in person here at Cornell, and he told me that the captive stock of ciliatus comes almost entirely from the Ille des Pines, and that mainland (northern and southern split distribution) geckos can be bluish. Whether that's true blue or not is once again, left flapping in the breeze...
:I am also afraid the literature on gekkonid colour change is thin at best. They may have numerous factors affecting colour change. Although your answer is extremely thourough, the fact of the matter is there CAN theoretically be a blue crestie. The variation in purple to lavendar hues in such geckos is at the 'low' end of the blue spectrum and let us not forget those remarkable day geckos with TRUE blue tails and spots. I'd have to agree with you on one point though, you probably not find a true blue crested, but with time I am sure there with be some pale 'blueish' types ready to gauge the market.
