Does anyone know how to use this function? What I was looking for was the ability to set the contents of a container field to be the .gif file that this function generates and have that container display the color of the .gif file.

Thanks Alex for the calculated container field usage. I also found out that I can do a Set Field [ table::ContainerField ; @RGB2GIF (255; 64; 255)]. That was my original idea.
