The 'shadow' one works fine and is changed, so I don't know what the issue is. *I didn't replace the '5 o clock shadow' facial hair, as it's very buggy for me and none of the colors seem to work correctly in CAS. Right now this is only available for male Sims, but I fully plan to update it with female when I get some time. Lavender is only available as a default replacement as I'm a newbie and can't figure out how to make it non-default. This file replaces 'pastel purple' in male hair, eyebrows, and facial hair* with a much more pleasing lavender. That's why I, a complete CC newbie, took it upon myself to rid the world once and for all of 'pastel purple' and replace it with an actual pastel purple/lavender. 'Pastel purple' has plagued me since I started playing - it had potential to be such a pretty color, but it wasn't.
That awful, pinkish-yellowish color that is 'pastel purple'. Thanks to Maxis, it's not really a problem!. If you're anything like me, your Sims just need to have fun colored hair.
