Question

what happens when a pigment reflects a certain wavelength of light? it produces oxygen. that color is the color we see the pigment as. the pigment absorbs that color it changes the lights wavelength.

Explanation:

Pigments reflect certain wavelengths of light. The color we perceive a pigment to be is the color of the light it reflects. For example, a green - pigmented object reflects green - wavelength light and absorbs other wavelengths. Producing oxygen is related to photosynthesis in plants and not to light reflection by pigments. Absorbing a color is the opposite of reflecting it. And reflecting light does not change the light's wavelength.

Answer:

That color is the color we see the pigment as.
