Tutorial: How to Shade Pixels
A lot of people have trouble with shading realistically. Lately the horrid trend of "pillow shading" has caught on. Not only is it ugly but extremely unrealistic. So I made this tutorial to help you shade!

1. Start with a pixel. I'm using this:


2. Zoom in.

3. Shade as if a light is shining down on your pixel from a certain place. How I shaded below I imagined that there was a light shining from the upper left hand corner. I placed a shadow color on the farthest side from my 'light source' and made it lighter closer to the 'light source'.

4. Zoom back out and save and you have your realistically-shaded pixel!
