Stormy Day
Moody colors are my jam. If you do digital lettering, you have lost of options for main color, 3D color and shading. If you do watercolor, a nice loose ocean design, or even a misty forest. Contrary to what a lot of people think, you don't need green for forest design, you can do it with blues, gray, even purple! If you do watercolor brush lettering, this would be a great color combo to use!
