In a CRT (cathode ray tube) monitor, the substance that produces light and color when struck by electrons is phosphor. The inside of the screen is coated with phosphorescent materials that emit light when energized by the electron beams generated by the cathode ray. Different phosphors emit different colors, which combine to create the full spectrum of colors seen on the display.

Is the colour of a flame based on how many electrons and protons there are?
The colour of a flame is not based on how many electrons and protons there are, however it is to do with electrons. When the electrons furthest from the nucleus of the atom are excited (in this case by the heat of the flame) they gain energy and "jump" up "energy levels". The electrons don't like this extra energy so in order to lose it, they emit a photon at a particular wavelength, which we perceive as colour.
