What color of glass-reflecting pan do you install to preserve the maximum photosynthesis and why?

Question

You are on a spaceship moving closer to the sun. Your food supply is supplemented by an on board greenhouse. The light intensity is increasing and for visual comfort, you must block out some sunlight. What color of glass-reflecting pan do you install to preserve the maximum photosynthesis and why?

Answer 1

It's to do with wave lenght of light. White light is a mixture of seven colours. Plants are green (usually) in colour. This means they reflect green light. So green would be a colour least needed.

I suggest you use a green reflecting pan.

Hope this is of some help to you.
