Colour Cube
ColourCube resources are used by both the EnvironmentSettings and PostFX to change the colour and tone of the world.
A ColourCube is a set of 32 32x32 textures forming a CLUT, which is usually colour corrected to give a different art style to the game at a given time (i.e., the red filter when wrecking a vehicle in versions 1.0-1.3 of Burnout Paradise).
Some time after the February 22, 2007 build of Paradise, ColourCubes were added to the EnvironmentSettings folder and were used specifically to give the game a unique art style.
In the 1.4 update to Burnout Paradise, the ColourCubes were changed to a standard CLUT, possibly due to the extended time cycle conflicting with the ColourCube's art style. In the 1.6 update, these were again updated to use a default RGB CLUT.

Data
In Burnout Paradise: The Ultimate Box on PC and Burnout Paradise Remastered on PC and PS4, data is in a standard RGB24 format (that is, each pixel takes up 3 bytes, one for each color). Textures in the PS3, Xbox 360, and Switch versions of the game are also RGB24, but swizzled. There is a functional implementation of an Xbox 360 to PC texture converter on GitHub.
