How do you make a blended rainbow?

Published in Painting Techniques 2 mins read

To make a blended rainbow, you can use acrylic paints, applying each color and blending the edges to create a smooth transition.

Creating a Blended Rainbow with Acrylic Paints

Based on the provided video reference, here's a breakdown of how to create a blended rainbow gradient using acrylic paints:

  1. Start with Primary Colors: Begin with the primary colors – red, yellow, and blue – as your base.
  2. Apply First Color: Apply your first color (red) to a portion of your canvas.
  3. Add Yellow: Next, add yellow next to the red and begin to blend the two colors together with your brush at their edge. Use a back and forth motion to soften the line and mix the paints, starting at the edge where they meet.
  4. Introduce Blue: Add blue and start blending it with the yellow using your brush at the edge between them.
  5. Mix Blue and Yellow: Blend the blue and yellow to create green.
  6. Blend Remaining colors: Add a small amount of blue to your brush and blend the green to make a more rich color. Now you have all the rainbow colors on your canvas.

Key Techniques for Blending

  • Soft Edges: Focus on creating soft edges between the colors to achieve a smooth gradient.
  • Use Enough Paint: Ensure that you have enough paint on your brush to allow for blending without any colors drying too quickly.

Example:

The video reference shows blending red to yellow, then yellow to blue. When done correctly, the intermediate colors (orange and green) become visible through the blend, completing a rainbow effect.
