Here are some retextures for the vanilla GTA eye colors. This mod replaces all of the weird color options but keeps the natural colors. Since I worked with the vanilla textures the quality and look will be the same.
Installation:
Drag and drop the ytd file here: \x64w\dlcpacks.rpf\mpbusiness\dlc.rpf\x64\models\cdimages\mpbusiness_ped_mp_overlay_txds.rpf
I provided a backup and the png files as well.
