Periodic hsv surf color

Is it possible to set hsv colormap in order to get a periodic changing color? The hsv that I'm using right now starts from red, then pink, blue, green yellow and red again while I would like to have a periodic repetition of colors, something like red, pink, blue, green, yellow, green, blue, pink, red.
This is particularly helpful when you try to plot angles. In my case for example I plot (using surf 2d) a field's angle that goes from -pi to pi but using hsv colormap I see a color jump between -pi and pi even if they represent the same amount.

hsv() is a built-in colormap. I suggest you don't change it. However you can build your own colormap that can have unique colors, colors in a gradient, or ranges of colors that repeat. See attached demo.

There are lots of functions that generate colormaps, like hsv(), jet(), summer(), winter(), etc. Or you can invent your own. Then you can use the N by 3 array to set the axes's colormap, or you can use it to replace the default color order like my demo did.
