Aquarius is a range of artist quality watercolours made by Roman Szmal. The majority of Roman Szmal colours are single pigment paints, which ensures clean mixing and lets artists easily create their own colour palettes.

Each colour is made with high-quality gum arabic and glycerin, linden honey, distilled water and pure pigments. Every pan is hand filled and labelled with watercolour paper.

The range contains a few unique tones such as PY61, PY168, PY181, PV37, PBr23 or PBk32. The 42 Earth Shades are made from natural earths, not synthetic iron oxides, and these pigments are found in many different places around the world. Some unique shades are created exclusively by Roman Szmal, such as Aquarius Green, Przybysz's Grey, Ocean Blue, Shadow Violet, Green Gold, and Olive Green.

Colours are made in small batches that allow them to be carefully checked. Every batch is tested for performance qualities: vibrancy, flowing abilities, viscosity, colour value, transparency, granulation, undertone, tinting strength, clarity and particle size. For each colour, Roman Szmal select the perfect grind to match the particle size.
