Art Lesson: Glazing and Color Mixing. Learn how color mixing and glazing create vibrant deep colors in underwater scenes. By using primary colors (red, yellow and blue) while painting this tropical underwater scene Wyland will demonstrate how water dilution levels and various color and paint mixing techniques work together to create proper paint consistency. Complementary colors sit opposite each other on the color wheel. Because they are opposites, they tend to look especially lively when used together. By placing complementary colors together, each color looks more noticeable. Cool color combinations such as blue, green, or purple can suggest the ocean. Warm colors such as red, orange, and yellow can evoke sunlight and warmth. Glazing is a technique used to build up many layers of color in a painting, creating a natural flow between two color tones. One way this can be achieved is by using water to dilute the paint down to a very thin, nearly translucent state. Building up the layers provides more control of the hue and shade of the painting. Let the different coatings dry before applying the next one.
