What happens if all of primary colours are combined?

When all primary colors of light (red, green, and blue) are combined, they produce white light. In terms of pigment, when the primary colors (cyan, magenta, and yellow) are mixed, they create a darker color, often resulting in black or a muddy brown, depending on the proportions used. This difference occurs because light is additive, while pigments are subtractive, absorbing certain wavelengths and reflecting others.
