A J Ludlow Quinacridone Rose Professional Watercolour

Quinacridone Rose is just one of the bright and exquisite Professional Watercolours made in the UK by A J Ludlow. Being based on a single pigment with excellent permanence and light fastness, ensures that this watercolour’s properties are exceptional.

Quinacridone Rose Professional Watercolour is prepared using a synthetic bluish-red organic complex, from the quinacridone-type class of light stable and high-performance pigments. This pigment’s colour is due to its γ-crystal structure, which gives it a strong intense red hue making it ideal for use in A J Ludlow’s Professional watercolour range.

First produced as pigments by Dupont in 1958, quinacridones can vary in colour from deep red to violet, depending on the nature of any substituent groups or a more subtle variation is seen with changes in the pigment’s crystal structure, as in the case of C.I. Pigment Violet 19; a γ-crystal modification produces an intense bluish-red hue, whilst a β-crystal structure results in a deep magenta colour.

Quinacridone Rose is one of the few organic pigments used in A J Ludlow’s Professional Watercolour range. Organic pigments tend to have smaller crystal sizes than inorganic and mineral pigments and so exhibit considerably high colour strengths and staining power. This is true for A J Ludlow’s Quinacridone Rose Professional Watercolour, as it has a high tinting strength and so is best used sparingly when initially mixing with other colours. Quinacridone Rose can be used as a primary red to create attractive purples when mixed with Phthalocyanine Blue (Red Shade) and beautiful oranges.
