PixaTool is a pixel art oriented tool useful for any “retro” styled projects, and at the request of FifthElephant, it now has support for the Quake palette if you wanted assistance bringing any assets into a more faithful state for your project.
Check out the source tweet below:

New #PixaTool Update (v1.3) . #8bit #pixel
( APP Info > https://t.co/EIhm82b0Yz )

As @GavinEdgington requested, added the #Quake 256 color palette. So now you can create textures compatibles for your projects.

Enjoy! 😉 pic.twitter.com/q0YX9sVFUx
