I missed these <3
There's enormous 108 colors, in sets of 6, all with system eyes, prim eyes, mesh eyes, and OMEGA appliers. Come try the wearable rainbowy demo, or pick yourself up a set or two in world at Devae. There are also some OMEGA mesh eyes there if you don't have any and want some! I actually prefer them - I find it easier to just have to adjust one set of eyes to my avatar, rather than every individual color, so being able to just wear a HUD and change my eyes suits me great! The OMEGA eyes are very inexpensive, so it's pretty easy to give it a whirl and see if it's for you.
You can find the OMEGA eyes vendor on the right side of the eye section (entering from the landing point) of the shop
