=== Intensities ===
The 0%, 50%, and 100% values in the above tables are "should-be" values. However, the real hardware doesn't exactly match that intensities. The actual intensities depend on the luminance mixing (R,G,B tied together via resistors), on chipset (classic CPC, or newer ASIC ones), and on the load applied by external hardware (Monitor, or TV set).
On an actual Amstrad CPC, the half-intensity colour signal is measured to be closer to 40% rather than the expected 50%. This was verified by Grim and independently confirmed by Nocash. [https://www.grimware.org/doku.php/documentations/devices/gatearray#inkr Source]
* [[CPC Palette]] - some more details
This explains why the Amstrad engineers used the following values to adapt the old colour palette to the new 12-bit palette on the Amstrad Plus:
* 0% became #0
* 50% became #6. They specifically chose #6 for the 50% value instead of the expected #7 or #8, to better match the real Amstrad CPC palette.
* 100% became #F

Note: We can observe that the official Amstrad names of some colours are a bit silly: "red" is in fact brown, "yellow" is in fact khaki and "white" is in fact grey.
