Color Expression determines whether Corel Painter should use the main or additional color in an image. Using Color Expression, you can introduce input (such as direction) which controls output when you apply two-color brushstrokes. You can control the variation between the main and additional colors in a brushstroke by adjusting Color Jitter. You can also smooth the variation between the main and additional colors along the brushstroke.

You can also link color variation in brushstrokes to audio input from your microphone, or internal audio such as streaming music.
Brushstroke color can change in synch with audio input.
