I made a set of defaults using the lovely SBC Eyes by
Helianthea (http://www.modthesims.info/member.php?u=9008739). I set new swatches to keep them easy to choose.
The basegame eyes are redone with my choices from her natural sets, and the 5 from the October patch were redone in a fun rainbow style for less human sims!
