I’m working on a project that requires me to select “unique” colors for each item. At times there could be upwards of 400 items. Is there some way out there of selecting the 400 colors that differ the most? Is it as simple as just changing the RGB values by a fixed increment?
Probably HSL or HSV would be a better representations than RGB for this task.
You may find that changing the hue gives better variability perception to the eye, so adjust your increments in a way that for every X units changed in S and L you change Y (with Y < X) units of hue, and adjust X and Y so you cover the spectrum with your desired amount of samples.
