One of the earliest pigments known to man, ochres are mineral oxides used in colors from the reddish brown to, in this case, yellow-brown range. This very opaque and lightfast color is often considered essential to a painters' palette. (Series 1) Equal the intensity of GOLDEN Heavy Body Acrylics but with an even, flowing characteristic useful for dry brush application, fine details, pouring, spraying (particularly when mixed with GOLDEN Airbrush Medium), staining techniques and many others. Fluids are created by loading an acrylic polymer binder with concentrated levels of quality pigments for a wide selection of permanent and lightfast colors. No fillers or extenders are added to achieve the desired consistency, nor is the fluid quality achieved with additional water. GOLDEN Fluid Acrylics have the same pigment load as the Heavy Body Acrylics, but in a viscosity similar to heavy cream. Fluids allow for smooth flowing applications while retaining color intensity, tinting strength, film integrity, and adhesion. Fluids blend easily with all acrylic colors, and readily tint gels, mediums, gessoes and grounds. Fluid Acrylics are extremely versatile, and ideal for fine brushwork, glazing, staining, water media techniques and many more. Mix Fluid Acrylics with Airbrush Medium for airbrush application of artwork including textiles.
