So if you have seen this
Then you should know about the fact that the palettes are all messed up and unfortunately I for the life of me I can’t figure out how to use them so I need some help, sorry if this seems a bit pushy.
If you’re using Fe builder you should copy paste the palette of generic enemies onto your unit’s custom palettes and edit it from there. Generally just feel out the coloring of them based on how shades darken and lighten with the default palette. Asking people to do all of your palettes is a tall order so picking up the skill yourself would prove beneficial.
