Colour is decided by the frequency of the electromagnetic wave ie light. There are cones and rods in our retina. The cones are sensitive to the frequency of the electromagnetic radiations falling on it. So colour is sensed by us. If there be any problem with those cones then colours cannot be differentiated. Such persons are called as colour blind people. Any way there is a limitation of sensing the frequencies. So right from red (lower freq) to violet (higher) are visible to our vision. Beyond these limits we cannot see.
Depends on the gasses making it up AND on the temperature. Remember all those "neon" lights that you see.
When you mix colored lights you add colors until you get white.
Red, green, blue.
green, blue and red
Visible light includes all the colors of the rainbow. The different colors are the result of different wavelengths.
Not particularly... the aurorae borealis is always there in all colors, only it's usually too faint to see.
no, because if you are color blind you might see the papi lights as different colors. (the papi lights are the lights at the end of the runway) you would also see the false horizon as the same colour therefore not accurately being able to see if you are level.
The lights of red and blue reflect off of the object into your retina and the rods and cones depict what colors your see.

you can use light splitters to see all the colors from white light. they're like those red and blue 3-d glasses.

There are many places to buy solar lights in a variety of colors. You can purchase a set of 12 solar lights that change colors from www.overstock.com for approximately $70.00.

If a boy and a girl both stood in a dark room, and then the lights were suddenly turned on, both would see colors at the same time (assuming both of their eyes are healthy).
red
it is a mixture of all the colors of the rainbow.
