artcher [175]

Answer:

Great question!The color of grass leaves (usually green) is mostly due to the absorbance of the other wavelengths of visible light by chlorophyll. Therefore, any differences in gene expression (that ultimately determine phenotype) that affect the concentration of chlorophyll in the leaf will, in turn, affect the color of that leaf. My guess is that, in the absence of light, you could still measure chlorophyll concentration, and assume what the color would be. However, you need transmitted (reflected) light in order to perceive color. I don't know, if a tree falls in the forest, and none is around to hear it, does it make a sound? Hope this helps. Keep the questions coming!
