Question:How to build a color legend based on angle.

plot color legend

I have generated a picture using pointplot and display that creates a grid of colors based on the angle between vectors and (1,0) in R^2. Each angle is given a unique color via the HSV color space. I would like to provide a legend explaining the colour, something along the lines of

red (brown) green (blue) red
0                Pi                 2*Pi

and possibly

red       (brown)       green 
angle1                     angle2   

Is there an easy way to do this, or will I have to mess around with a custom pointplot/textplot solution?
