NOTE: This update contains a fix to a bug that was on the last update due to the code improvement I did. This bug has been reported by a fellow plugin user of UltraColor, who has wished to be anonymous. Thanks again for your help!
If you are using the 1.1.6 version of the plugin, I strongly recommend updating to this version!
Fixed | NullPointerException occurred when someone did /color and /gradientcolor.
