[Help] Hexagonal Math for Color Swatch

Here is an example of what I want to accomplish:

Is there an easy way to use gradient fills to approximate this display?

I'm going to try using 360 radial gradients with each drawn in a triangular "slice" of the hexagon. The color at the edge of the hexagon will always fade to white in the center, so it should look fairly accurate.

The reason I don't want to use an exported graphic, like the above image, is because the graphic is not as accurate in its representation of the colors within the hexagon. People will be using the hexagon to select custom colors, so the visual representation has to be accurate to the data that is available to choose from.

This is a bit of a brute-force method, but are there more efficient alternatives in mx '04?
