Watercolour Comparisons 4 - Burnt Sienna

Burnt Sienna is one of the most useful colours in the palette. Whether you are using a limited palette with one of each of the primaries or a split palette with a warm and a cool of each of the primaries, Burnt Sienna is fabulous addition. You can see all these swatches, along with other earth colours, on my website here.

It is possible to mix a burnt sienna hue using a yellow and a red to make an orange, then adding ultramarine to create a neutralised warm brown. But it is much quicker to use a single pigment paint.

There are a number of options. Burnt Sienna should be made from PBr7 - a natural earth pigment that is also used to make Burnt Umber, Raw Umber and Raw Sienna. Heating the Raw Sienna pigment creates the burnt Sienna. Some companies use PR101, (which is also used to make Indian and Venetian reds) to make a Burnt Sienna Hue.

My preference is for the earthy look of PBr7. Mixed with Ultramarine it creates a warm Indigo, burnt umber hues, lovely greys, stormy sky colours, shadow colours and so on. With a yellow it creates raw sienna hues. With a phthalo blue it creates cool greys and browns. With a crimson it creates earthy indian reds and burnt reds...and so on. Alone, just mixed with water, it creates a perfect skin tone.

So which is the best? That depends what you like to paint, whether you like granulation or not, whether you want a more orange colour or a more neutral burnt orange colour.
 Burnt Sienna Options - Top line: Burnt Sienna M.Graham PBr7, Burnt Sienna Old Holland PBr7, Burnt Sienna Rembrandt PBr7, Burnt Sienna Hue Art Spectrum PR101, Transparent Mars Brown Mameri Blu PR101, Burnt Sienna Winsor & Newton PR101, Quinacridone Burnt Orange Daniel Smith PO48
Bottom line: Hemetite Burnt Scarlet Daniel Smith Genuine Hematite, Transparent Red Oxide Daniel Smith PR101, Enviro-Friendly Red Iron Oxide Daniel Smith PBr6, Burnt Sienna Daniel Smith PBr7, Burnt Sienna DaVinci PBr7, Italian Burnt Sienna Daniel Smith PBr7.

It is clear the options range from an orange through to more red-based browns with more or less granulation. Transparent Red Oxide provides a wonderfully granulating version with a definite orange hue, Hematite Burnt Scarlet is also highly granulating with wonderful colour range. Quinacridone Burnt Orange goes all the way to the orange side so will not neutralise so well, but is quite a popular option for those who don't like granulation, as is the W&N Burnt Sienna (hue).

One of the best tests though is how the colour works with Ultramarine and other blues. Here is a range of colours possible with Burnt Sienna mixed with Ultramarine, Phthalo Blue and Cerulean - classic blues in the palette. It is the deep greys and browns and blues that I am looking for with Burnt Sienna. Notice how lovely and granulating the Art Spectrum Burnt Sienna Genuine is. I loved this colour but it didn't re-wet as well in the palette as the Daniel Smith and Da Vinci so was superseded. Also notice that Burnt Umber (hue) is readily mixed by adding Ultramarine to Burnt Sienna so is not necessary in a limited palette.
Burnt Sienna mixed with blues - Ultramarine, Phthalo Blue, Cerulean.

 Here is Burnt Sienna with Cerulean. Note that Burnt Sienna creates wonderful greys with Cerulean but with that with Quinacridone Burnt Orange it makes greens rather than greys.
Burnt Sienna and Quinacridone Burnt Orange + Cerulean. 

You can see Burnt Sienna and Phthalo blue on the second line below. Since Phthalo blue is cooler than Ultramarine it will create cooler blues and greys, including creating a raw umber hue.
Phthalo Blue mixed with a range of brown pigments - Burnt Umber, Raw Umber, Burnt Sienna, Indian Red, Raw Sienna and Burnt Umber.

My favourite is Daniel Smith for a rich earthy version, or Da Vinci for an equally rich earthy but slightly more orange version. Both of these are PBr7. I also love Transparent Red Oxide for special effects so have that as an extra when painting, as well as the DS Burnt Sienna that is always in my palette.

Happy painting!

Aquarelle palette - my pigments sorted! Updated.

I have a lot of paints that I only use occasionally, and had been trying to work out a way to store them that is neat and functional for occasional use at home, but that also allows me to take them to my classes or workshops when I am teaching. These didn't need to be in a palette, but some sort of good storage system. I am very grateful that Malcolm Carver, a fellow member of the AWI,
presented me with the answer with the flower shaped Aquarelle palette he designed.

This palette is intended to encourage his students to work with a limited palette of 12 colours and to mix them on the paper rather than in the palette, so there is no 'mixing' space.

They hold up to approximately 2 full pans of paint, can keep paint moist, keep paints covered when not in use and are neat and portable. Perfect!

I don't use them for doing a regular painting. I have set up many of them with my extra pigments - colours that are perfect for a particular painting for me or for my students; pigments that are really granulating; primatek colours etc. It may be possible to mix the colour, but the properties make them useful and can't be created by mixing others. They contain many cadmium colours that I use to demonstrate opacity or for special effects in a painting.

I set them up using one for yellows, another with yellow earths. A third has oranges, another has reds, purples, blues, greens and so on. It makes it much easier to find a pigment or colour in a demonstration or while painting.

Happy painting!

Sketching in a Glass exhibition

I have been busy working on a number of paintings for upcoming exhibitions, but in between I have continued to enjoy sketching with the Sydney Sketch Club. These were painted at an exhibition of Art Glass at Angel Place in the centre of Sydney.
