Any color but pale or teal are shades I like and would use. Basically anything from ice cream green - Tiffany blue and anything in between but Aqua/turquoise is a safe bet for a color. Any shade bright or light...there will be something similar and blend able for either gender.
Subway Tile to swoon over! Lose the white and use Bluegrass for a rich and deep blue green color with high gloss. Handmade tile has a unique look and pairs beautifully with copper kitchenware, house plants, and rustic barn wood.
