How to draw a color wheel in illustrator?

How to draw a color wheel in illustrator? I am thinking of creating many small arcs with gradient and all hue colors. Any ideas?

Answer

One way would be to apply a linear gradient on the stroke. Create a circle, and stroke it with a gradient pattern. Make sure the gradient has the stops like in the table and picture below. The gradient might not look as smooth in the transitions, but that's all that comes to mind.

+------------+---------------+----------+
| Color Stop |      RGB      | Location |

|------------+---------------+----------|
|      1     | (255, 0, 255) |    0.00% |
|      2     | (0, 0, 255)   |   16.67% |
|      3     | (0, 255, 255) |   33.33% |
|      4     | (0, 255, 0)   |   50.00% |
|      5     | (255, 255, 0) |   66.65% |
|      6     | (255, 0, 0)   |   83.33% |
|      7     | (255, 0, 255) |  100.00% |
