There are 256 possible levels of red, green, and blue and each is independent of the other, then there are 256 x 256 x 256 different color combinations that the computer can theoretically display. 256 x 256 x 256 = 16.777 million colors.
 
From your answer, I will just assume you do not know anything about PCs and are talking about today's PC.
a.k.a. not the older PCs.
Older PCs using old standards e.g. EGA has only 16 colors.

As for todays PC colors, you can get up to around 16.777 million colors (true color). like already mentioned above by PaulieVideos.

In simplest terms.
Your screen has a pixel resolution say 1920x1080 (so 1920 wide and 1080 high).

Pixel means Picture Element.

A Pixel is really 3 colored LED lights that are close enough together so that they appear as on dot.

Each of the 3 elements in the pixel (Red, Green and Blue) can be set to one of 256 levels, from fully off to fully on.
The Graphics card is responsible for refreshing the monitor a number of times per second (>30) to produce the picture you see.

There is a lot of complex and clever engineering and science that is worth reading about.

Some screens work by actively generating colored lights, others work by blocking off light.

This is highly simplified conceptual description.

Hope it helps.

each colour has 8 bits, so the standard is 24Bit (one for each component). If you really need more levels than that you get a more sensitive digitizing device.


Is there any reason for asking these questions? Do you have a technical problem that we can help with?

If you know the make and model of the CPU, you simply look it up.
Otherwise, you have to turn the PC on.

May I ask...what is behind all these questions? What are you looking for here?
