Bob's 14 landscape colours are specifically formulated to a stiff but smooth consistency, necessary for the Ross technique. Background colours are heartier in body than the lighter highlight colours. These pigment rich colours yield an endless number of natural colour combinations and all are non-toxic.
See below for 37ml colours.
Bob Ross Landscape Oils Large Tubes are also available in 200ml.
Smaller tubes are ok for beginers if your doing smaller paintings, would recommend the larger tubes for people doing lots of paintings on larger canvas. Rob Cassie (London, United Kingdom) on 4 Feb 2013
Great oils but would recommend larger tubes if doing lots of paintings. Rob Cassie (London, United Kingdom) on 15 Jan 2013
