Final answer:
The color wheel, an essential tool for illustrating color relationships according to the Law of Color, consists of primary, secondary, and tertiary colors. Developed by Isaac Newton, this tool helps in understanding how colors interact and convey meaning in art and design.
Step-by-step explanation:
The tool used to support the Law of Color and illustrates how colors are related is the color wheel. Developed by Isaac Newton in 1666, the color wheel explains color arrangement and the interactions between colors. The wheel consists of three concentric circles; with the primary colors (red, yellow, and blue) at the center, followed by the secondary colors (purple, orange, green) which are obtained by mixing primary colors, and finally the tertiary colors, which result from mixing a primary color with an adjacent secondary color. An alternative to the color wheel is the color tree, created by Albert Munsell, which illustrates colors through tints and shades on connected planes.
Understanding color in art and design extends beyond the hierarchy of mixing colors. It includes the study of color interactions and associations, which can differ globally and are essential in conveying different meanings and emotions in artistic expressions.
