I would love some duochrome eye shadows as well - I've been having to cut into makeup time due to workout time, but don't want to cut shadows altogether, oh no! I found Discover (GWP) in my stash by accident, and I've been using it a lot: blending it into the crease gives the impression of a darker color. More like that, please! I would love some yellow and bright golds (no olives), peaches (like sunnywille), something like cougar (neutral with a kick).
Cream shadows in more neutral but not too light colors would be fab. I'm thinking Mojave, Cameo, Latent, that sort of stuff.
I would also love cream Climax and cream Rosie - my skin prefers creams during the winter
I wonder whatever happened to candle light glow (or something like that): it was a gwp glow a while back, in the golden range but more subdued than liberty. I like to add that to my finishing powder sometimes or use it as highlighter.
Na Na Na Boo Boo is a nice one to keep permanent too: it's sort of a mlbb with with a bit of lilac hue. And while we're talking GWPs, I would like to not run out of Discover, it's a great winter color for me
It may be too late for skin care stuff, but have you considered making moisturizer that includes retinol? Ya know, for our lazy types who don't want to go through the proper steps and don't mind sticking it out for the slower results?
