Please update the CSS optimizations in NUglify to optimize colors.
The shortest methods of including a color in CSS are either with the color name (red, blue, etc.) or with a 6- or 3-digit hex string (#f0f0f0, #e00, etc.).
All CSS colors, except those that include an opacity, should be converted to the shortest color represented either by name or 6- or 3-digit hex string. That would include colors defined by RBG notation (using specific numbers or percentages) and possibly HSL.
RGB is pretty simple to convert to a hex string, which can then be evaluated for possible shrinking to 3-digits or converted to the corresponding name.
