I like green. It’s the color of my birthstone, it looks nice on me, and it reminds me of spring and trees and plants and the ocean and all sorts of nice things.
I second purple. It’s dark, a little mysterious, but not as boring as basic black. It’s elegant when used tastefully. The color of royalty. And to my delight, very in style right now.
My favorite color has always been purple, ever since I was a little kid. I used to love a deep, royal plum purple, but lately my favorite color is a pale lavender. Particularly when lavender looks almost blue.
