Reverting color box function in Lotus 1-2-3

I am using Lotus 1-2-3 installed on a server. I can be able to change the colors but now when I clicked on the color box, there is no color to select. The color box appears to be empty. The computers in my network are running Windows XP SP2 and the server works with Windows 2000. The version of the Lotus I am using is an older version. How can I revert the color box function?
