How can I increase the brightness of a color without increasing perceived saturation?

I'm working on a website that lets users set their own page colors. They only pick a handful of colors, then I'm offsetting the brightness (converting to hsv, add/subtract v) for things like shaded boxes, lines, faded text, etc. The problem is that in HSV, when you decrease brightness, the perceived saturation decreases (and when you increase brightness, the perceived saturation increases). How can I create these offset colors while making the saturation appear the same as the original color? Is there a formula for this? Should I be using a different color space?
