Black Pastel





Baby males ~$150 (or cheaper), females ~$200+

Other cheaper single gene morphs (baby males will always be cheaper than males with size or females):

Cinnamons are also a darker morph that has lots of nice chocolate tones.
Mojaves are darker IMO and some have high yellows and some have high whites (flames)
Het Red Axanthics are usually darker with a cool look, almost normal-like but at the same time very unique
