The heat capacity of a room is the same, whether it's lighted or dark, although a lit room will be warmer than a dark room (all other factors being the same).
Adding mass to a room will change its heat capacity. More mass will slow down a temperature change. Less mass will speed it up.
it is better to study in a light room because when you are in a dark room you can't see anything
Germs multiply much quicker in light (daytime) and lessen in number in darkness. So it is better to keep your room dark (switch the lights off) when you are not there. Talha
If there is no light you can not see. There is only blackness. This is quite disconcerting. If you put your hand in front of your eyes you can not see it. If the room is dark ie no light then you can not see.

I believe that this is a personal preference, but I think a very cold room can be distracting, just as a really warm room can also be distracting. My suggestion as to the room temperature of a "study room" would be to reach for somewhere in the middle of "cold" and "hot." Of course since these words mean different things to different people, your ideal "study room" temperature may not be mine.
Green, it's brighter then red, so green is more noticable. I get this from my older sister's room, her lamp changes color. when the red light is on, the room is pretty dark. But when the green light is on, the room is very bright!!

Light colors reflect and dark colors absorb.
Turn on the light and walk out the door.
You are in the dark.
you get the glow stick
Turn on the light and walk out the door.
Black will be the color of a yellow object in a dark room while white light falls on it.
Green will be the color of a yellow object in a dark room while red light falls on it.

Because light is being reflected from the surface. If you paint a room black, light will be absorbed by the black and the room will be dark.
This is a simple answer. Our eyes require the reflection of white light from an object in order to see it. If there is zero light in a room that is totally dark we can see nothing.
