CSS colorizer
CSS colorizer modifies the colors inside your cascading style sheet applying hue and adjusting saturation and lightness.
Notes:
- resulting color code is always in the #rrggbb hex format
- named colors are not parsed, so they won't be converted
- small rounding errors may occur (i.e. choosing an hue of 160 you may obtain 159 or 161)
- backing up your style sheet is always a good idea before overwriting it with the one produced here
