The original PC with Color Graphics Adapter could generate 16 colours in Text mode, 2 in High Res (640 x 200), and 4 in Medium resolution (320 x 200) as well as the seldomly used low resolution 160 x 200 (16 colours but only on TV/Video).
CGA had however a palette of 16 colours that could be used to select colours in all modes but High-res that was only black and white.
Of a remote association to the above (And to the topic as Amstrad bought Sinclair so there's the connection) the Amstrad CPC had the same chip used in the CGA and its modes were fairly similar, however there was a bigger palette of 27 colours there
