We didn't find any evident documents about the RGB values that produce the C64 colors, only assumptions and approximations. Unfortunately we even found that none of the coders of converters or emulators truely took pains about to come up to the original colors. Loudly colored isn't enough in our opinion, and doesn't deal to those extra-ordinary C64 painters!

We put big efforts in our handmade approximation. It depends on a 1702 monitor (on the part of the C64), and a 1084 plugged to an Amiga 2000. We tuned both parties to an optimum, and then tried one after another to tune in the correct hue on the Amiga, quite to match the C64 color. These values are the results, and after all all of GoDot's color capabilities depend on them. One who uses them can rely on first class converted pictures!

C64 color Red Green Blue
black $00 $00 $00
white $ff $ff $ff
red $88 $00 $00
cyan $aa $ff $ee
purple $cc $44 $cc
green $00 $cc $55
blue $00 $00 $aa
yellow $ee $ee $77
orange $dd $88 $55
brown $66 $44 $00
light red $ff $77 $77
dark gray $33 $33 $33
gray $77 $77 $77
light green $aa $ff $66
light blue $00 $88 $ff
light gray $bb $bb $bb

"Likewise we determined the order of GoDot's colors by view, this time we took a C64 and a C128 (using the mentioned 1084). We ascertained that basicly colors are emitted in 9 different intensities (shades of gray). Go and dial off hue on your monitor when GoDot's palette requester is on screen. You will be left with 9 shades of gray you can easily tell from another (these are just the colors of the default palette for Colors: 9). Hence there are seven colors with partners who have the same shade of gray. Now, we didn't order the two partners arbitrarily but according to physical computations. PC or Amiga may show different results. Who cares?"
