Can I change the color of paint in the can?

The only way we recommend changing the color of our paints is to mix like paints, ie. Mixing Brightside with Brightside. We do not recommend addition of "universal" tints or pigments into our products. Yacht paint products are formulated to withstand harsh conditions and additions of universal tinters or any such products may affect water resistance, long term durability and may also slow down the drying time of the paint. We would also strongly discourage anyone from adding anything to antifouling paints that is not already mentioned on the label. Apart from affecting performance such additions may be illegal as antifouling paints are registered with a unique formula and addition of unauthorized materials, especially active ones to "improve" performance changes to this unique formula.
