If you want to call them peach, call them peach. Sounds like a perfectly good name. Shrug. I'd personally stay away from the hypo portion of it and let peach stand on its own as hypo caramel lavender, myself. Since we haven't seen an adult caramel lavender, abjectly naming caramel lavenders "peach" and the hypo caramel lavenders "hypo peach" seems a bit premature to me since you're supposing what the non-hypo version will turn out like ...and we've been burned there before. What if the caramel lavenders end up being the color of cow plop instead? I'd also avoid "phase" as it implies selective breeding, which these are not.
On a side note re: your demanor and presentation of the morph--
Personally I don't give a flip what you call them. As you say, it's your right to name them, but your continued attitude is childish enough that I wish you would take your ball and go home. Why I'm even bothering to post this as it will make zero impact, I'm have no idea, but it's all the input I have and will have on the matter. I wish Rich Hume would come on here and discuss hypo +/- caramel lavenders and their naming, he's a pleasant man to talk to and would greatly benefit your cause as a spokesman.
