As I mentioned in a previous post, I am intentionally capturing photos of summer colors.This post will highlight the primary colors, red, yellow, and blue and a sampling of my photographs follow. They are considered primary colors because they can’t be created by mixing other colors together. There are warm and cool variations of each color.

The primary colors mixed together create the secondary colors (orange, purple, and green), as well as the tertiary or intermediate colors. Four engaging investigations follow: Go here and here for a simple color mixing activity that introduces the concepts of hydrophilic and absorption.

Go here for a favorite color mixing exploration. Name the colors you create.

Go here and here for an investigation that creates a chemical reaction as you mix colors.

Go here for a fun experiment with milk, soap, and the primary colors that explores surface tension.

However, these colors are not the same as the primary colors used in printing and digital displays. Go here for an investigation with the primary colors of light.
