    Trying to deal with Sprite files on non native hardware...

    Thanks.

    Artworks will tell you.

    How about Wimp_ReadPalette?

    Ok... But need entries for all 256 colours, or a program I can feed these 20 values into that will spit out RGB values for all colours displayed in !Paint colour selector.

    The target for this would be Linux or possibly Windows. So need to know how to "expand"...

    The desktop pallette is 16 colours, regardless of screen mode.

    or a program I can feed these 20 values into that will spit out RGB values for all colours displayed in !Paint colour selector.

    Ah, so you /don't/ mean the desktop pallette.

    My memory of this is a bit rusty, but isn't the colour number from 0 to 255 composed as %BBGGRRTT, giving two bits each to blue, green, red and "tint".

    Then your three colours are formed by rearranging four bits each:

    red% = %RRTT0000
    green% = %GGTT0000
    blue% = %BBTT0000

    I'm fairly sure that you'll find it documented in the PRMs -- which, unlike ArtWorks, are free online.

    That's correct, and it's in the PRMs.

    However that's in terms of the old Archimedes 12bit colour system. If
    you want the palette to cover the full range of 24bit RGB, i.e white is
    proper white rather than a very light grey, use:-

    red% = %RRTTTTTT
    green% = %GGTTTTTT
    blue = %BBTTTTTT
