Color is mostly a biological sensation. In low light, humans lose color acuity because rods are activated more than cones. Objects reflect the same wavelengths, but our cones can’t activate due to low energy. Does this mean color fades in low light? It depends on the physiology of the perceiver.
Humans have three color receptors peak-sensitive to red, green, and blue. Dogs have only two: yellow and blue. This means they can’t distinguish certain wavelengths. To dogs and colorblind humans, red and green look the same because their receptors are activated similarly. Color isn’t just a property of light; it’s a biological perceptual experience.
Ableism. As disability advocate Imani Barbarin says, if bigotry is the goal, ableism and eugenics are the toolkit. If you look at the history of any form of systemic bigotry, the justification for human atrocities almost always boils down to “well these people can’t contribute to society, so they don’t deserve to be a part of it.”
