Mitch Albala's "Color Harmony in Landscape: Understanding and Working with Color Strategies"


Fri-Sun, September 10-12, 2021

9:30am - 4:30pm

To capture the qualities of color and light, landscape painters must modify the colors they see. To guide these color choices in an informed way, painters rely on a color plan or strategy. In this workshop for artists working in oil, acrylic, or pastel, you’ll learn how the colors you see in nature or a photo are just the first step toward a complete color strategy. Through a combination of exercises and small paintings, you’ll learn the practice of color grouping; how to create palettes “tuned” to the particular harmony you are after; how relationships like analogous or complementary colors are just one part of a complete strategy, and the importance of neutral harmonies to help create unified light.

This is not a workshop for first-time painters but, is ideally suited for those who work either en plein air or in studio and want to expand their color knowledge. This workshop is open to oil, acrylic and pastel painters.

Here is a link to Mitch Albala's Book "Landscape Painting: Essential Concepts and Techniques for Plein Air and Studio Practice":
