Gleambow does not solve the problem if you need thousands and thousands of a particular color or colors that are never going to spawn on a sovereign due to planet color algorithms put in place by the old development team to make planets look a certain way and as a result exclude colors from ever happening. If we were talking about a single shade of red outside of the 20 other possible reds it might be one thing, but we are talking about a basic color when it is white. That is a problem in my opinion, created by an unnecessary algorithm used for both permanent and sovereign planets.
The intent of the algorithm was to prevent “ugly” color palettes on planets and create some similarities between planets of similar type. While I can understand this to a certain degree with public planets, sovereign planet owners have the ability to change the colors on a planet anyway so why restrict the colors that might spawn? Make it equally likely that any color can spawn or just allow sovereign planets the option to pick any color. You increase the range of colors stores can stock by doing this.
