Summary: Game-specific 'EGA' palettes for Amiga versions

Initial Comment:
A recent build added an Amiga-specific palette for 16-
color games which seemed significantly higher contrast 
than before (bright colors brighter, dark colors darker); 
these were likely taken from one specific game (in my 
case, not Amiga Indy3).

The colors in the current snapshot are (RGB444, taken 
directly from scumm/gfx.cpp):
000 00C 0C0 0CC C00 C0C C60 CCC
666 66F 0F0 0FF F99 F0F FF0 FFF

In Amiga Indy3 [v1.4], the colors should be (RGB444, 
captured from WinUAE):
000 00B 0B0 0BB B00 B0B B70 BBB
777 77F 0F0 0FF F88 F0F FF0 FFF

As I don't own Amiga versions of any other games 
(Maniac Mansion, Zak McKracken, Loom), I don't know 
what they use 

It's certainly possible that each 16-color Amiga game 
used a slightly different builtin palette; the appropriate 
palette could be selected based on the game loaded.

The current Amiga palette was produced by comparing colors 
values of screenshots of Maniac Mansion under WinUAE and 
Maniac Mansion under Dosbox with Color Picker tools under 
Gimp. Looks like my attempt was flawed though, as I just 
notiiced the colors in WinUAE screenshots change slightly 
when I pasted image into Gimp.  
How would I convert those RGB444 values into a color table 
for ScummVM ? a patch would be welcome, as I'm very new 
at this.

Just a suggestion: ScummVM could use external palettes if
present in the game data directory. Make it a simple text
file which just lists the colors in such RGB hex triples as
posted here. This way everyone easily could tweak them for
their own.
