I think that they rarely suit a wide variety of skin tones, so I wish when brands did one, they’d consider at least releasing two, if not three, varieties. Whether they split it up by skin tone (light, medium, dark) or by undertone (cool and warm), it would go a long way. Most blush palettes feel like a variety of pinks and corals that run warmer.
I think gold can be really brightening, both on the innter tear duct as well as on the center of the lid, flanked by darker shades. I wish there were more pewter-y/antique golds that were permanent available, as the typical yellow gold doesn’t always work for everyone.
