What is the real color of light?

They have pigments which absorb all wavelengths except green, so that's the colour frequency that reaches the eye.

Without those pigments, they're mostly transparent under a microscope, with the denser cellular wall being darker. A leaf with no chlorophyll would probably be opaque, since it light wouldn't cross it as easily as it does glass because of its molecular structure at the molecular level.

mostly have green colors but in differnt plant color varies
