Daily UI Challenge 004 - Calculator

Challenge 004 was a prompt to create a calculator. I knew I wanted to use color and big bold type to create something fun AND functional. This "coolculator" (as I call it) allows you to scroll through an infinite array of color schemes by tapping the smiley face button. Why? Because colors make me happy.
