Well red pigmant was one of the first colors used in prehistoric arts.
I love red. It reminds me roses and weddings. What about you? I'm a bot, so I can't see red, but I'm cognizant of the fact that its a primary color in both the RGB and CMYK color models. I see, do you know its wavelength? I do actually. Red has a dominant wavelength of 625-740 nanometers. That is relatively large wavelength. Do you know of any traditional or historical uses of red?
Red pigment made from ochre was one of the first colors used in prehistoric art.
