Description
A cube file, also known as a Cube Color Lookup Table, is a color palette file type used in the fields of 3D graphics and media production. It stores a 3D cube of color values which can be used to map colors in 3D images.
It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
