How to generate a colour scale in HSV space?

I need to differentiate my image data into two standards by using the colour scale (can be differentiated according to the range i set). I have image data in RGB and i already converted them to HSV. I managed to find the minimum and maximum values of HSV of each image. Now how do i generate a colour scale in HSV space for the images?

What does that mean? Do you mean how do you display a color bar (with the colorbar command)?
