Do you mean a primary color? If so they are red, yellow, and blue.
SuperGoob - The primary colors of light are red green and blue, however the primary colors in terms of pigment are red, yellow and blue. It's the difference between additive and subtractive color mixing.

I must agree with Super Goob on this. I have always been taught that RED BLUE and GREEN are the prime colours from which all other colours can be made ( i know you get green from mixing yellow and blue but that's paint not pure colour).
However to further complicate the matter there was a scientific report on BBC radio 4 that announced some institute had found a forth primary colour. It hadn't been named at the time, but was described as that mucky brown colour you get when you mix all the others together. Black and white are not colours, they are the absence of light (black) or complete spectrum of light (white). Don't confuse colours of man mad substance with pure light colours.

Why is everyone saying red blue and yellow?
The primary colours are RED, GREEN and BLUE. If anyone has had an old TV and switched it off you can scoot up close and see the little groups of colours - Red Green and Blue make up all the colours you see on television and RGB as its known is the normal colour space for image work on computers. People have mentioned CMYK this is to do with printing as its subtractive rather than additive - Wikipedia as an ok explanation. That is Cyan, Magenta, Yellow (see? NOT a primary) and Black which is arguably not a colour at all but I say again this is in terms of printing and different media.
Red, Green and Blue added together make WHITE. This has been known since Isaac Newton proved it conclusively but really you have to keep in mind we're talking with abstract colours or light - if you mix red green and blue paint together you'd get a horrible brownish mix.
The colours of the rainbow will have the entire sequence of colours from red to violet. That of course is only part of the spectrum - it goes beyond what we see as ultraviolet and infrared prove - they're both invisible to us but certain animals can see in to the ultraviolet including birds and insects.
I can see theres a lot of confusion on the issue of colour. I'd recommend a book on colour by Philip Ball but I haven't read it. I know what I do from a background in science and photography.

Prime colours are red yellow and blue. They are simply the three main colours which all of the other colors are made from. The rainbow colors are the basic spectrum of colors that light can produce.

primary colours are red blue and yellow all colours are made up of these colours. the rainbow is a bending of light. red blue and yellow are there but blended together to make the secondary colours orange green violet.White is an absence of colour and black is all three red blue and yellow mixed together.

A primary colour is a color that cannot be created by mixing other colors together. primary colours are red, blue and yellow. neutral colours are black and white all other colours can be obtained by a mixture of the above.

Prime colours are red, yellow and blue. ie those colours that cannot be made from mixing other colours. HOWEVER, when it comes to photography you will find a spanner in the works. The 3 colours there are magenta, yellow and cyan and you get blue from subtracting yellow from cyan. All very wierd stuff.

There are only 3 primary colours and they're in the rainbow, but have different names Red is called magneta, blue is called cyan and then yellow (has no other name)

Prime colours are three .They are green, yellow and red.They are nothing to do with the rainbow. These colours are the main colours our eye can see mostly or optic nerve has more attraction to these colours

PRIMARY colours are red blue and yellow. Almost all other colours are variants of these three depending on how light hits them apparently
