Mixing digital colors is similar and different than mixing paint colors. Paint colors are subtractive when mixing and digital colors are additive when mixing. I've been working to develop a library for mixing digital colors. The image from yesterday was experimenting with tetradic color sets. Today, the image below is formed from a core pattern of 4 pairs of squares. Each pair contains a large and a relatively smaller square. A random color is selected for each pair and a complementary color is selected. Complemtary colors are located opposite of each other on the color wheel. The color selection is repeated for each pair of each pattern. The pattern is repeated 16 times.
