I usually reach for this tool whenever I need to assign colors programatically to a series of elements e.g. calendar events, object type labels, etc. and want to see how the color distribution looks for a certain number of objects.

Just adjust the number of color swatches to approximate the number of items you have —if known— then find a palette that looks good for your use case.

Or use it as a tool for copy-pasting the generated values :)
