Motivation I’d like to find a way to take an arbitrary color and lighten

Motivation

I’d like to find a way to take an arbitrary color and lighten it a few shades, so that I can programatically create a nice gradient from the one color to a lighter version. The gradient will be used as a background in a UI.

Possibility 1

Obviously I can just split out the RGB values and increase them individually by a certain amount. Is this actually what I want?

Possibility 2

My second thought was to convert the RGB to HSV/HSB/HSL (Hue, Saturation, Value/Brightness/Lightness), increase the brightness a bit, decrease the saturation a bit, and then convert it back to RGB. Will this have the desired effect in general?
