While January’s birthstone, garnet, comes in a variety of colors, amethyst ranges from very pale, pinky-purple to deep purple (that can look almost black in lower light). The most prized amethysts are “strong reddish purple” per GIA, so saturated enough to be distinctively purple but not so dark that it looks black in lower light. Some of the lighter and paler amethysts remind me of a purplish-taupe, while the brighter, more saturated stones look almost magenta-purple.
About This Series
Each look idea is centered around a “quad” of four shades with the expectation that one might bring in the appropriate brow bone or additional transitional shade based on skin tone. I know that I tend to use more like five or six shades in a typical look, but I think that four is a happy medium to give a good idea of the “core” color scheme of a look while giving you the ability to lighten/darken as desired. I have listed the colors in this order: inner lid, middle of lid, outer lid/crease, and crease/above crease or lid.
You might see combinations that seem slightly repeated but placement will vary (e.g. a halo placement where the lightest and more shimmery shade is placed on the center) as placement can also create a different effect/look! You might also want to consider incorporating your favorite matte/shimmer shades (as applicable) to increase the versatility of certain palettes. Consider these ideas a jumping off point!
