*[https://www.grimware.org/doku.php/documentations/devices/gatearray Minor difference in colorimetry between CPC and Plus] On CPC (not Plus!), green half-intensity is significantly higher than red and blue half-intensities
*Major difference in colorimetry between the real Amstrad displays and emulators display. CPC DiAG shows clearly why, by demonstrating the weak response of Amstrad monitors to the Red component:

* CPC DiAG also shows that the primary colours themselves are a bit different. Blue is more vivid and Green is less fluorescent on Amstrad displays.
* Colours are less saturated and black is not as profound on CRT monitors than they are on modern displays.
* 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), affecting dithered colours. This effect is absent on LCD displays.
* The usual scanline effect of CRT monitors is barely noticeable on the Amstrad CTM colour monitor. But it is very pronounced on Amstrad monochrome monitors.
* The slot mask is the texture that is visible in the CTM colour monitor. CRT masks do not exist on monochrome monitors.
