After a little big of digging and some Photoshop tidying up I have an image that is essentially my approximation of the Atari 256 colour palette from the 800XL. I’m sure that this colour palette may have been available to other Atari home computers but I don’t have that knowledge.
It’s a beautifully rich palette and something that I intend to use as a basis for my future games.
Something that I’ve always wanted is a fancy tool that allows me to capture an indexed colour scheme and then order it based on any number of criteria. Photoshop allows me to sort based on Hue or Luminance but I really want to sort based on the actual colours used. Black through white, blues, reds, greens etc
At Acclaim we had a wonderful in-house tool that allowed us to play with colour palettes and export them to any number of formats. I’ve yet to find a decent palette manipulation tool out there.
