Information about Matisse Flow & Structure Formula Paints.
Lightfastness. Opacity. Permanency.
Only the finest quality pigments and ingredients are selected for the Matisse range of premium artist acrylic colours. All have the highest lightfastness rating of ASTM 1 or 2. All Matisse paints are fully compatible with the range of Matisse Mediums working together to create a highly versatile painting system for all artists.
The lightfastness, (permanency of colour or resistance to fading) in paint, is rated in several different standards, however the most popular methods are:
- ASTM (American Society for Testing and Materials); or
- BWS (Blue Wool Scale).
ASTM ratings range from ASTM I to ASTM V, with pigments that are rated ASTM I being considered to have excellent lightfast qualities, and those rated ASTM III-V being considered fugitive. The BWS scale ranges from BWS 8 (excellent lightfastness) to BWS 1 (fugitive). For a paint to be considered artist quality, it should be lightfast, or permanent, with an ASTM rating of I-II or a BWS rating of 8-6.
Matisse paint labels indicate the lightfastness rating given to the pigment content of each colour and ASTM ratings have been used whenever possible, with the internationally recognised BWS rating being used when the ASTM has not tested a particular pigment for use in acrylic paints.
All Matisse Flow, Matisse Structure, Matisse Background and Matisse Ink pigments are rated either ASTM I-II or BWS 8 so artists can be confident of creating lasting works of art.
Matisse Structure & Flow Formula - Brilliant colours, unique formulas
The intense, vibrant colours of the Structure and Flow Formula paints cover the full colour spectrum, including several uniquely Australian colours.
Matisse Structure Formula is a rich impasto paint most like oil paint. Matisse Structure Formula paint is ideal for application with a brush or palette knife for striking textured effects or combined with the range of Matisse Mediums for exceptional flexibility of application and finish.
Matisse Flow Formula is a low viscosity acrylic paint that glides from the brush. Matisse Flow Formula paint is ideal for mural work, canvas painting, geometrics, hard edge, photo realism and fine detailed painting - in fact any art that requires intense smooth colours.
Although in most cases these two ratings will be the same, there are some pigments in a pure, dry state that may not maintain the same opacity when incorporated into acrylic paint. This may be due to variations in particle size between the pigment and other raw materials in the paint formulation, the intensity of pigments or the pigment loading in the paint system. These can all have an effect on the resulting opacity of the paint.
To help artists identify the opacity and transparency of Matisse Acrylic colours two ratings have been made available.
Pigment opacity rating: This denotes the actual rating that would be given to the pigment particle (and the aggregate for blends) when studied on a macroscopic level or as described by the pigment manufacturer.
Paint rating: this rating describes the resultant opacity of the actual paint.
In addition to this, some colours will be different in shade, tone or even opacity even though they have the same name or generic colour index name (i.e. PY74). This is because this index for pigments is an indication of chemical type and basic shade only. The hue, tone, intensity (and opacity) can vary considerably between individual pigments classified under this index. In addition brands of paint with the same pigment number can vary due also to the use of fillers and other agents and the quality of the pigment used. Matisse use only the finest pigments available and limit fillers, when they have to be used (for rheology, in-can stability, flow control etc) to the bare minimum and do not use fillers to extend the colour, which generally results in dirtier, less intense colours.
