red
Facade colors whose dominant hue is red, including pale, dark, bright, dull, and predominantly red mixtures.
The category of red colors covers all shades whose dominant hue is closer to red than to any other basic color. It includes light and dark reds of any brightness or saturation, as well as mixtures of reds with other colors where the overall result is mainly red.
Brightness and saturation can vary widely. Carnation and maroon remain in the family despite their different lightness.
Another hue can be present as long as the overall color is mainly red. Distinct areas or patterns of several colors follow the separate facade-color rules.
