Hi! As I promised, here are the hair colors I use. There 6 blonde shades, 6 brown shades and 3 red shades. The downloads include installable .sims3pack files and the hex codes, for those who don't use the Launcher.
This may not look good in hairs with that use adjust-shine instead of highlights. And for some hairs (like Peggy's) it would look better you enchance the highlights (make darker/brighter)
Not all the hairs will look the same with this colors, some may look great and others not so good, depending the original UV Map and a bunch of complicated stuff :P
Have fun! ^-^
PS: The CAS thumbnails I used on the pics are like... brighter than the actual colors, so don't pay attention to them XP
