008 Can magnets change the color of light?

A color CRT (Cathode Ray Tube) is coated with three different phosphors which emit red, green, and blue light respectively. These colored pixels are often arranged in configurations as shown below.Three electron guns (one for each primary color) direct electrons towards their intended pixels to form the intended image.

Being negatively charged, moving electrons in a magnetic field will experience a magnetic force. As such, a magnet near CRT will deflect the electron beams away from their original intended paths, resulting in the electrons hitting a pixel at a different location and color from the original intended pixel.
