Each color has its own shades
1. Brown eyes - almost any color will suit, but purple, graphite, green, pink or garnet shades are best. Dark brown eyes blend nicely with pistachio, golden colors, and blue. Use only vivid tones, not pale.
2. Green eyes - dark blue, lavender, maroon, brown, peach, copper, and shades of gray all suit nicely.
3. Blue eyes – enhanced when underlined with gold, lilac, and pink. Soft shades of brown go well.
4. Gray eyes - very versatile, and there are many color choices. You can use clean steel shades, black and silver, blue, and yellow. However, bright ad vivid shades should be avoided.
If color matching the iris of the eye is applied to the lower eyelid, the eyes will shine, and appear brighter and deeper.
