Green
Pigments in plastids absorb various wavelengths of light.
blue-violet and red-orange
The pigments used absorb some wavelengths of light and reflects the rest back to your eyes.
In cells, chlorophyll is particularly important.Chlorophyll looks green to us because it reflects a lot of green light, absorbing relatively little. The longer (red) wavelengths and shorter (blue) ones are better absorbed, and it is these wavelengths that are used predominantly by a plant for photosynthesis.There are several types of chlorophyll, as well as other light-absorbing pigments such as carotenoids which are red, orange, or yellow. When chlorophyll breaks down in the fall, these other pigments become visible, giving the variety of leaf colors that you see on deciduous trees in that season.Pigments
The pigments something reflects is the color of that object. The cactus is green, so it reflects green and uses every other pigment for photosynthesis.
Because it contains the plant pigments anthocyanins, which reflect red wavelengths
Antenna Pigments
Different pigments absorb light of different wavelengths.

These pigments absorb specific wavelengths of visible light while scattering the remaining light.

Chlorophyll a & b, caroten and xanthophyll are photosynthetic pigments used by plants. These pigments capture various wavelengths of solar radiation for energy transformation.
Different pigments respond to different wavelengths of visible light.
