Titanium White No. 1 is the most brilliant white in the Harding range, suitable for crisp, cool opaque light hues, ground with Safflower oil a pale, slow-drying oil.
As Safflower oil is a paler yellow than linseed oil, lighter pigments (whites and soft blues especially) maintain their brightness when mixed.
If you want a powerful mixer that lightens hues actively, then this is it. Although not subtle, this white is the most suitable for a bright, fresh palette. It forms a strong and durable film when cured. PW6 is an Inorganic pigment.
