There are several online tools for converting between RGB and HSV, if you don't need to do this automatically. The first three google hits seem to do this:

http://web.forret.com/tools/color.asp

http://www.yafla.com/yaflaColor/ColorRGBHSL.aspx

http://www.csgnetwork.com/csgcolorsel4.html

If you don't know the RGB value of orange, or any other color, then you could use a color picker.

This actually has an HSV converter as well.

And orange is 256/128/0 in RGB or 30 (degrees), 100%, 100% in HSV.
