It might help if you would state the printer brand and model in the title of this post.
Just a generic statement, but did the color work fine just before you installed black?
I assume this has a black and color cart, not 4 carts?
Try to remove, wipe contacts with rubbing alcohol on the color cartridge and reinstall, perhaps the printer doesn't think you have a color cart installed.
(my hp 845 would do that occasionally and there was a software setting to tell the driver there was a color and b/w cartridge installed as opposed to one or the other)
Good Luck
