What is the .COL File Extension?

.COL File Extension Description:

The file extension COL has the function of storing RGB values for entries in the color palette of the Autodesk Animator program. The Autodesk Animator is an application designed for 2D animation and painting. Originally, the Autodesk Animator can run on a machine under MS-DOS. The first version of the Autodesk Animator uses 320X200 pixels with 256 colors in its color palette. The Autodesk Animator Pro, which still uses the COL file extension, on the other hand, has the capability to store almost any resolution and color depth palette.

The Autodesk Animator and the Autodesk Animator Pro make use of the COL file extension though the file formats are different. Looking at file sizes can check the difference between files with the .col file extension used in the Autodesk Animator from those files used in Autodesk Animator Pro. The Autodesk Animator is using a file with the .col file extension when the size is exactly 768 bytes. Conversely, the file extension COL within the AutoDesk Animator Pro has varying file sizes; that is, they can be larger or smaller than the 768 byte file size.

In Animator Pro, the file with the .col file extension stores the palette information and this file can begin with an 8-byte header. The Offset, Length, Name, and each with its own accompanying description can define such header.

* Offset: 0; Length: 4; Name: size - the total size of the file, as well as the header

* Offset: 4; Length: 2; Name: magic - the file format identifier

* Offset: 6; Length: 2; Name: version - the version of the color stage format

When the version input from the file with the .col file extension header is included, it can denote the level of the color data in each RGB component; thus, when set to 0, it can indicate a 256-level color data.

Aside from the file header included within the file with the .col file extension are the palette entries written in the form of "rgbrgb..." order. Each component of the RGB is a single byte within the range of 0-255. In the original Autodesk Animator, the COL file extension only has the capacity to include each RGB values within the range of 0 to 63.
