How to create your Rainbow Pixel Art
Step by step tutorial for creating an easy rainbow pixel art in a heart shape
Total Time: 35 minutes
Start with a sketch
Using a pencil, eraser, and ruler draw your shape, I chose a heart here, and then create a grid inside of it. That’s where the ruler comes in handy! This would be much easier if you used a dot-grid journal though 🙂
Add color!
With your marker, apply just a touch of color into the center of one of the squares (pixels) and then paint over it with water. You can alternately use colored pencils, crayons, or anything else here.
Continue adding color
You can randomize the colors you add, as I did here, or go in a particular order and create a pattern of a kind.
Erase those pencil lines
Once the watercolor has dried, you can go in with an eraser and remove all of those pencil guidelines we drew in the beginning.
