^^' Well my fursona is biased on my favorite colors, but at least I placed one semi-natural color in...which is pale peach. I thought they complement well with each other. Now, some of the ones I see is like "Rainbow barf in my eyes".
Eh, I think a sparkle-anything is any bright colors that is more than 3. Most in visible areas too, not minor like mane or nose. More of the body, tail and face. Black and red isn't bad in my opinion, but yellow red and green? Beh.
(Why am I lazy to check boards!? XD Eh well, laptop battery going to die anyways unless I steal my sis. My charger died.)
