There could be different reasons why you would be interested in learning how to use a limited color palette. From reducing the supplies weight in your bag when drawing on location to a better understanding of color interactions and how you achieve color harmony in your artworks, so that they look engaging.

In this class, I will show you a simple method of choosing the best colors for your sketches. This method works for any materials - from traditional watercolor, gouache and acrylic paints, colored pencils, and markers to digital Procreate, Photoshop, etc.). 

The palette limitation will help you understand and use colors more effectively. It's a basis. Later, you can extend it to a wider array of colors in your palette. Or, if you'll like drawing with a limited palette a lot, it might become your unique art style.

So, in this class, you will learn:

• how to read the color wheel;
  
• how colors interact with each other;
• how to create your own color schemes based on existing color harmonies;
• how to use thumbnails to make better artworks; and
• how to apply colors to create visual effects that will make your sketches look stronger.
