Art Spectrum, an Australian oil paint manufacturer have a range of 13 different oil colours that they developed with inspiration from the Australian landscape. I have used their colour Australian Red Gold for years and it is one of my absolute favourites. It is an amazing glazing colour that goes from deep red when laid on thickly to an amazing warm yellow as it is spread out thinly into a glaze. I use it as my main yellow and orange in most of my paintings and you can build amazing vibrancy when building it up in multiple layers.
I recently had a look at their page dedicated to all their Australian colours and it looks like they have an amazing range. I am particularly excited about Flinders Red Violet and Australian Green Gold. They all seem to be particularly well suited to landscape painting and aren’t too bright and dominant like the pure cadmiums.
