1. You need to apply a color mask, telling the fluff strands where to apply to color. 2. You need to reference a gradient index. 3. Using the sculpt tool, you can now paint using COLOR_T and COLOR_ALPHA.
COLOR_T tells the strand where to pick the color from the gradient (on the color mask). COLOR_ALPHA tells how much to use that color (on the color mask).
Alternatively, you can colour the area that you will put fluff in as the colour you want it coloured. That way, the fluff will just take THAT as its colour.
