Art Spectrum® Liquid Spectrum Inks are brilliant, water-resistant, non-toxic, lightfast ASTM 1 & 2 colours that have twice the pigment concentration of standard ink ranges.
The colour strength allows them to be diluted to watercolour-like washes or used undiluted to make bold, vibrant artworks.
When intermixed and used in conjunction with Art Spectrum® Liquid Spectrum Metallics this range creates an unlimited vibrant palette for the artist. Blue Wool Scale ratings of 6,7,& 8 are considered permanent for artistic purposes.
*Always shake well before use
