I was looking for the hardware color values:

For me the hardware color codes are wrong, so I grabbed out my cheat sheet I used 30 years ago:
https://ia800504.us.archive.org/BookReader/BookReaderImages.php?zip=/8/items/Happy.Computer.N40.1987.02-Cartman/Happy.Computer.N40.1987.02-Cartman_jp2.zip&file=Happy.Computer.N40.1987.02-Cartman_jp2/Happy.Computer.N40.1987.02-Cartman_0030.jp2&scale=2&rotate=0

Check the table at the bottom left.
Example:
Color 6 (Bright Red) has hardware value 0x0C, but not 0x4C. Obviously the wiki has added 0x40 to the value. I am confused.

No, it's ok.
The hardware value is a 5bits value (bit 0 to 4).
But, to select INKR (colour selection mode) with the Gate Array, you put bits 7,6,5 to %010. So you add 64 to hardware color value.Your table is wrong because it's not a hardware colour value, but a hardware colour value+color selction table ;)

Thank you for clarifying this  :)
