Phthalo Blue paint is good for many Saltwater fish. Semi-Opaque series of waterbase Polytranspar colours exhibit good hiding ability with a moderate spray, and may be freely intermixed with any other Polytranspar colours for special blends. These colours are non-bleeding and may be sprayed lightly or thinned to produce semi-transparent effects. The pigments in this waterbase paint are ground and polished up to five times longer than other pigments, assuring you of higher gloss, cleaner colours and a smooth-flowing airbrush with fewer clogs. Elastomers give flexibility to the dried paint, for thicker, glossy layers without cracking.
