Question

similarities and difference in colour

Answer 1

Explanation:

olors only exist in our brains visual cortex. Light has different wavelengths. Our eyes have specific cones which detect certain wavelengths. When a cone detects a certain wavelength or combination of wavelengths, it sends a specific signal to our brains visual cortex. When our brain receives this specific signal, it creates a specific color. You can't mix colors. You can only combine different wavelengths of light, resulting in a different color.

It changes the wavelength or combination of wavelengths the substance reflects towards our eyes. So a substance reflecting all wavelengths of light, appears white in the visual representation created by our brain. Adding pigment to the substance makes it absorb some wavelengths and reflect the rest. The rest, being reflected, is detected by our eyes, which now send a different signal to our visual cortex. The substance, in our visual representation, now appears red or blue, etc.
