I personally pick from one family of colors I know works for certain eyeshadow shades. I find corals to be excellent with nearly every color, especially greens; while super dark smoky eyes or really dramatic dark blues need paler, pink or peach neutral colors. I find blues work great with pinks or peaches, when they’re lighter rather than darker. I always like to have a slightly purple lip if I’m going for pink or purple on the eyes (or might go with a full on bright pink – just depends).
