GOLDEN Fluorescent Acrylic Colours are a soft-body, highly-pigmented dye with polymer coating that produce intense, brilliant colours. These colours are formulated for maximum intensity and vibrancy of colours, helping your artworks stand out! As these GOLDEN Fluorescent Colours have a transparent finish, applying them over bright white surfaces will allow artists to achieve greater intensity of colour. Note these colours are not lightfast, and a topcoat of varnish with UVLS (Ultraviolet Light Stabilisers) is recommended, though this will eliminate the ‘glow’ of the fluorescents under black light. Intermixing these or adding them to other paints will reduce the glow effect also. GOLDEN Fluorescent Acrylic Colours can be mixed with GOLDEN Airbrush Medium for airbrushing projects. Otherwise, simply apply with a brush or roller to your surface! The photoluminescence of GOLDEN Fluorescent Acrylic Colours is caused by the absorption of ultraviolet radiation and shorter visible wavelengths which are then emitted as longer wavelengths within the visible spectrum. These emissions appear as intense, brilliant colour. Available in a range of bright colours, these GOLDEN Fluorescent Acrylic Colours are sure to liven up your space!
