A J Ludlow Cadmium Yellow Professional Watercolour

Cadmium Yellow is just one of the bright and exquisite Professional Watercolours from A J Ludlow. Being based on a single pigment with excellent permanence and light fastness, ensures that this watercolour’s properties are exceptional. As with all our fine-art materials, Cadmium Yellow watercolour is lovingly handmade in the UK by a skilled artisan from the best ingredients and finest pigments.

Cadmium Yellow professional quality watercolour is supplied in a 15ml glass jar, because:

• The watercolour’s wet mass tone can be seen through the walls of the jar;
• The colour can be easily transferred from the jar to the palette with a palette knife.

But more importantly, there is no need for unnecessary additives or formulation changes to make processing in our colour manufacturing workshop easier, allowing the Cadmium Yellow watercolour made by A J Ludlow, to be at the highest pigment concentration and the pigment’s unique properties to be uncompromised. Anything less would be at odds with the brilliance and performance demanded of a professional quality watercolour range.

This Professional Watercolour is prepared using the mixed crystal inorganic pigment, cadmium zinc sulphide, which gives the watercolour its rich yellow colour and opacity. It therefore affords an opaque watercolour, which is semi-opaque in thin washes (as can be seen in the figure 1a below).

The Cadmium Yellow watercolour does not lift out completely (as can be seen in figure 1b above) and so has a propensity to stain the watercolour paper slightly.

This watercolour has a fluid consistency and is easily transferred to the watercolour palette. The pigment used in this watercolour is relatively heavy and so has a natural tendency to separate slightly on standing in the jar. If this occurs, just stir the watercolour gently in the jar with a clean palette knife until the watercolour is fully homogeneous again.

Cadmium Yellow is a bright and intense Professional Watercolour with excellent tinctorial strength, keeping its strong, vibrant colour when applied in diluted washes. With respect to colour “temperature”, it is generally regarded as a mid-tone yellow and often used on the watercolourist’s palette as a brilliant mid-shade yellow, which can be mixed with blues to give a selection of bright greens or with reds to create warm oranges.

Although containing cadmium, this metal’s bioavailabilty in the pigment used in our watercolour is very low and so the pigment is considered safe for use in our Professional watercolour range.
