that's an interesting project. i'm willing to help here.
i've got a male celestial with 3 pure colors. i wonder if breeding him with a pony with a pure color and a gray color could result in this(all my misties so far were obtained by gray+normal color breeding) XD if anyone wants to give it a try, LordPureTrio has indigo coat, cyan mane and yellow eyes(all pure).
and i have a water male with white coat, 0,99,0(green) mane and indigo pure eyes.
also, anyone got a male with indigo pure mane and gray coat/eyes?(pegasus or celestial)
so i could try this with indigo moon all well(she is all indigo with indigo pure mane)
