My belief is for a lot of graphics work a palette of five hundred colors is sufficient. Any more and the colors are too similar to matter.
Here is my palette. It is made up of the named colors used for web page design, plus the RAL Classic colors used in architecture, plus extra colors selected to fill gaps in coverage.
