As an art student this upsets me on so many levels. In the RYB color wheel there’s secondary colors (green, orange, purple) and tertiary colors (red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet). Black only exists in the absence of light while white only exists in the purest form of visible light. Neither are considered colors but can be added to colors to create shades or tints. I bestow my knowledge upon the people of the comment section.
