There isn’t a universal standard for what color grease means what. Some brands may have their own color schemes (eg. red for high-temperature grease, or using colors to indicate thickener types). Other brands simply use color as a marketing thing—for example, Lucas Oil makes their signature “red and tacky” grease, which is red as you might imagine.
