I prefer working with oil paints on canvas. I enjoy the versatility of oil paints and the media, and usually use a very restricted palette of primary colours. I enjoy mixing secondaries and generally avoid ternary colours.
Preferred yellows are Indian Yellow and Cadmium Yellow. Reds are Permanent Rose and Permanent Alizarin Crimson. Blues are mostly Phthalo Turquoise, Indigo and Cobalt. Occasionally I also use Viridian Green and Phthalo Blue for mixing. My universal white is Titanium White.
I have a love-and-hate relationship with Umber, Sienna and Ochre but use them occasionally.
Preferred media are natural turpentine, Damar varnish, Linseed oil and Daler & Rowney Alkyd Flow Medium.
