Color hex calculation

I have a picture, i choose a color on the picture like: 

#18212d
rgb: 24 33 45

when i colorize that picture by increased hue with 6 (202 => 208), saturation with 4 (25 => 29) (using photoshop), old color above was turned into new color:

#19232c
rgb: 25 35 44

Have any ways to calculate a new color of another old color after colorized? I need that to colorize all my css file.

You need to convert all your colors to HSV, manipulate it and convert it back to RGB. You need to understand how different color system works. This page is a good reference,

This page lists all the algorithms. You can also find open source code in just about any language you use. For Javascript, Dojo, YUI all have conversion functions built-in.
