If you want to channel the look of an actual stained glass window, this version is it. Bold black outlines frame each section, while pops of color — from pinks to teals to soft neutrals — fill in the panes with floral or abstract designs. The effect is most striking when sheer, jelly polishes are layered over a neutral or clear base, "the more opaque the base color is, the more vibrant the stained glass colors will be," says Kandalec. You can keep them glossy or switch to a matte finish for extra drama, but either way the result is bold, artistic, and impossible to miss.
