Matisse Fluid Acrylics - Series 4Matisse Fluid is our most liquid-like paint, yet despite its texture, it is highly pigmented. Each colour has an ASTM rating of I or II indicating Very Good Lightfastness to Excellent Lightfastness and are completely opaque when used directly from the container. Matisse Fluid is available in a brilliant range of 35 colours and they are completely compatible with Matisse Structure and Flow formula paints, can be either blended together or used by itself on the same artwork.Matisse Fluid Acrylics, have a very smooth, runny but slightly dense viscosity. Being highly pigmented, the colours will appear dark and intense on initial application but can be spread easily with a brush or mixed with water to reveal the colour graduation. The intensity of the colour is what makes Matisse Fluid ideal for tinting. The consistency allows precise drop-by-drop addition to any of the Matisse range of acrylic paints and the precise ratio of tint to paint can be easily replicated.This is the third tier in the Matisse range of Artists acrylic Paints. The thickest is Matisse Structure Formula, which has a thick dense consistency ideal for impasto techniques, followed by the Matisse Flow Formula range with its smooth cream-like texture and a thinner viscosity to allow free flowing brushstrokes or use through an airbrush (with minimal dilution). This allows the paint to be used for fine brushwork with or without water dilution. This paint gives a fine flow with a low-sheen finish and good levelling.
