I added a few drops of Rangers Adirondack Alcohol ink into each one, stirring with a cocktail stick. As the alcohol ink dries quickly, the Flower Soft particles absorb different levels of ink, resulting in a mixed tone.
Here is the original colour, together with the three colours I made using Stream, Lettuce & Cranberry inks.

The coloured Flower Soft can be used on their own or you can mix your own blends.
