I've experienced a little of this. My first garter was from Charlevoix county and was dark green with some fairly bright yellow. No orange. My second was from oakland county and was more of a matte inky black with not as much yellow. That snakes coloring was more pronounced than the first right after a shed.

These are 13 scrubs all born a couple weeks ago. Some are neutral some are green. Two have some really pronounced orange. Obviously the genetics of the father (whom i don't know) is interwoven here.

Being a relative newbie I wondered what else people might think about the coloring. It seems like the orange might be referred to as flaming.
