Found this in my trash bin.
By the time I was able to afford the license to Zinc (which allows to convert flash programs into standalone apps) the company went out of business so I'm unable to take it any further. This tool is provided here without any additional promises, warranties or support of any kind. Use at your own risk. No there's no Mac version.
Instructions:
Run the SwatchMaker executable
Use the color picker to create a color of your choice. You can also type in the Hex value directly. (typing in hex value will not update the preview but still works)
Press the checkmark to run the process.
Look in the folder, you'll find an swf named CLR_XXXXXX (whre X is the hex value of the color)
Drag and drop the SWF file into CTA2
Go into prop composer and assign a Render Style to the main color. For example if you want to use that color to change a characters Skin Color, then assign it Skin 1.
Go to the main scene and use the "Apply Selected Renderstyle" option to take that color and apply it to any character or prop on the stage.
You can easily create entire reusable color libraries this way, just save the swatches as custom props.
