CSS Colorizer is a tool to assist in picking colors for CSS. Colors can be related by defining formulas, so changing a single color can affect all other colors in the style sheet.
If you've used CSSColorizer before, you can paste in your generated CSS and the colors will be parsed. If not, you can put your CSS directly into the Internal CSS frame.
ParsePaste your CSS. Then, replace the color codes with color variables. Variables begin with '$$'.
