/* Colorimetry */
* On CRT displays, bright pixels will spill on their neighbours while dark pixels will get eaten by their neighbours (ie. bright pixels are bigger than dark pixels on CRT displays). This effect is absent on LCD displays.
* The usual scanline effect of CRT monitors is almost unnoticeable on the Amstrad CTM colour monitor. But it is very pronounced on Amstrad monochrome monitors.
* The shadow mask is the texture that is visible in the CTM colour monitor. The shadow mask does not exist on monochrome monitors.
