How to calculate RGB Hex color variations using Javascript / jQuery

Question

I am trying to programmatically create some css borders and text shadows (for compression effect) using jQuery.

Given the RGB color value, I would like to calculate the color variations as 0to255 does .

For example, given the color # 023f74 , how do I come up with 4 shades easier than # 0363b7?

perhaps you could convert the color to RGB ro HSL or HSB / HSV, then apply the variation and then go back to RGB!
