Last active Aug 1, 2019
This hubl macro will determine text color based on a set background color. This macro is based off of this sass color function by John W Long https://gist.github.com/jlong/f06f5843104ee10006fe which is based off of this article http://www.nbdtech.com/Blog/archive/2008/04/27/Calculating-the-Perceived-Brightness-of-a-Color.aspx
