Oh ... didn't know I had hit new land by getting Chocolate brown from Regal Purple. O_o
Sorry, after I didn't see anyone say anything I took her out from some Hunting before deciding to feed her again. Looked at the color values and saw that Blue in Chocolate Brown seems pretty low ... so assuming that feeding her 4 pears did MORE than just one step I decided to feed her 1 berry before going to bed.
Woke up this morning to find she was REGAL PURPLE again! Had I seen your reply I would have given her pears again to get Chocolate Brown and snap a pic :/
I was 3 kinds of annoyed with this color and multi procs on 1 food didn't seem to get her far enough away from it so I gave her 1 ValFruit to lower red and boost the Green/ Blue, a Pear to lower red and boost green to get them more even and 1 berry to boost blue ... She turned Charcoal Gray.

But don't worry, with my luck she will be back to regal Purple in NO TIME and if (well, when >_>) that happens I shall make it a point to feed her a pear to see if I can get Chocolate Brow again.
If I hit Chocolate Brown again I will remember to try this after Snapping a Pic, thanks!
