I love blue, it goes with anything. It's one of my favorite colors. When ever I draw my favorite flowers(sunflowers) I always use some type of blue color and draw checkers all around the flower. I usually end up using indigo.

When I would color a sky, I always chose indigo because of the exact shade of blue that it is. My grandparents all lived in the mountains and that is the color of the sky on a bright, summer day.
