| The category color is represented by a three element tuple enclosed by parentheses. A color is represented using the [[wp>RGB_color_model|(R, G, B) notation]]. Each one of the tuple elements corresponds to one of the color components. The first element represents the red component, the second component represents the green component and the third and last one represents blue component. Each color component must be in the range [0, 255]. Ex: (255, 0, 0), (128, 128, 128) etc. The color (0, 0, 0) is black and the color (255, 255, 255) is white. | The category color is represented by a three element tuple enclosed by parentheses.

| + | [[Table Type]]: | ||
| + | |||
| + | Conversions can occur either from Table Type or to Table Type. For this Table type, the structure must contain the following columns: | ||
| + | * "*#real" (category value): Represents the category value. | ||
| + | * "#string" (category name): Represents the category name. | ||
| + | * "#real" (category red color): Represents the category's red color component in the range [0, 255]. | ||
| + | * "#real" (category green color): Represents the category's green color component in the range [0, 255]. | ||
| + | * "#real" (category blue color): Represents the category's blue color component in the range [0, 255]. | ||
