Re: Green? Blue? Brown?
"Proxima Centauri really only produces red light"
No. I keep hearing this and it is totally incorrect. The light from Proxima has a colour temperature of about 3000K which is rather whiter than a halogen light bulb. The last time I checked, plants in my living room, at night with the light on, still looked green and my white ceiling still looked white. Sure, the light is redder than sunlight, but it's certainly not red light.
On the other hand, a cool brown dwarf with a temperature of a few hundred degrees probably would have these properties, but Proxima is far from being one of those.
