What is a .8bct file?

The .8bct file extension is associated with Corel PHOTO-PAINT, a powerful image editing software. Specifically, these files store color table information, which is crucial for managing and applying palettes of colors within the application. They allow users to save custom color sets or import predefined palettes for consistent color usage across various projects. While not directly an image file itself, it plays a supporting role in the image creation and editing workflow within Corel PHOTO-PAINT. These tables are essential for tasks requiring precise color control and replication.

The structure is proprietary to Corel PHOTO-PAINT, and while they are simple data files, they are not intended for direct editing or viewing outside of the parent application.
