Just Paint's March 2016 article “Painting on Location with QoR Modern Watercolors” included a suggested palette of six QoR paints selected for their own attributes and for their ability to create a spectrum of beautiful saturated colours. This article will first discuss the selection process, and then demonstrate the paints’ mixing potential when organized around an artist’s colour wheel.
Selecting the Paints
Paint colours rarely cooperate fully with an artist’s attempt to organize them into mixing systems. Not every blue and red will create a vibrant violet or every red and yellow, a lively orange. That is not to say mixes producing less saturated colour cannot be beautiful and are not intrinsic to a watercolour painting. However, while artists may easily dull down a paint, we cannot readily make the paint on our palette more saturated. Starting with paints that allow for bright mixes can expand the potential we bring to painting.

It is rare to find a pigment that creates a true ‘primary’ paint capable of clear mixes on both sides of the colour wheel. A red that makes both vibrant purples and fiery oranges, for example, is hard to find. One way to compensate for this is to have two paints for each primary colour: a blue that leans toward violet to mix violets, and a second blue that leans toward green to mix greens. How do you determine if a colour is predisposed toward one or the other side of the colour wheel? Through mixing tests. Using a green-biased blue with a green-biased yellow will result in a more vibrant green. A less saturated and more muted green would be the result should an artist use a violet-biased blue and/or an orange-biased yellow. These muted blends are quite lovely, and can really make a painting sing. However, the colour might also devolve into mud when the artist is not paying attention to how the mix is used.
QoR Color Mixing Studies
Initially we desired two saturated paints for each primary colour (red, blue, yellow). This would give us six paints that would combine to create strong secondary (violet, green, orange) and intermediary colours (yellow-orange, red-orange, yellow-green, blue-green, red-violet, blue-violet). The QoR watercolour line has many vibrant colours, so mixing tests helped guide our selections. We also needed at least one pair of paints on the colour wheel to mix a chromatic black.

Once we selected finalists for the primaries, we found that our mixing tests were not providing a satisfactory black. We knew from previous experience that QoR Ultramarine Blue and Transparent Pyrrole Orange create a beautiful chromatic black that granulates (from the blue) and separates in interesting ways while drying. If we removed the orange-biased red in favour of QoR Transparent Pyrrole Orange, would the orange mix with Quinacridone Magenta to create a vibrant orange-biased red mixture? We found that it did. We made the switch, and had our palette of colours!

A Six Paint Colour Wheel
Our color wheel is built from six paints: two blues, two yellows, a violet-friendly red, and an orange.

The two yellows:
- Yellow for greens: Cadmium Yellow Primrose (PY35, ASTM LF-1, semi-transparent, non-granulating, staining)
- Yellow for oranges: Cadmium Yellow Medium (PY35, ASTM LF-1, semi-transparent, non-granulating, staining)
The two reds (and an orange):
- Red for violets: Quinacridone Magenta (PR122, LF-NA although our tests show LF-excellent, transparent, non-granulating, staining)
- Orange-leaning Mixed Primary Red: mixture of Transparent Pyrrole Orange and Quinacridone Magenta
- Orange: Transparent Pyrrole Orange (PO71, LF-Good based on our tests, transparent, non-granulating, staining)
The two blues:
- Blue for violets: Ultramarine Blue (PB29, ASTM LF-1, semi-transparent, granulating, semi-staining)
- Blue for greens: Manganese Blue (mixed hue, PG7 and PB15:3, ASTM LF-2, transparent, granulating, non-staining)
Since pigments have different mixing strengths, combining equal amounts of two primaries might create an intermediary rather than a secondary when one of the paints overpowers the other. It is important to use your judgement as you mix. To create violet, we mixed violet-friendly Ultramarine Blue and Quinacridone Magenta until the mix seemed to lean toward neither blue nor red. To create green, we mixed green-biased Cadmium Yellow Primrose and Manganese Blue until the green colour appeared to visually balance between the primaries. Intermediary colours were then mixed to fill the step between each secondary and its primaries.
To create the colour wheel itself, we brushed the paints and mixes out onto damp Arches Natural White 140 lb (300 gsm) Cold Pressed Watercolour Paper. Painting onto damp paper contributed to the velvety look of the most saturated washes. Once dry, the paper was cut to shape and adhered to a fresh sheet of watercolour paper using GOLDEN Heavy Gel (Matte). A board placed over the freshly glued collage flattened the papers as the gel dried.
Conclusion
The painters in the Materials and Application Specialist team of GOLDEN are paint geeks, and they love mixing colour. We hope this colour wheel will be both informative and inspirational. Share the joy of colour and mix some QoR paints of your own! What happens if you substitute other yellows for the Cadmiums in the palette? Which yellows mix more vibrant oranges? Which yellows are friendly to green? Take notes as you mix, and your explorations will be resources you can return to in the future. You might even take this one step further, and explore glazing two colours rather than physically mixing them. In watercolour, there can be a difference between the colour created when physically mixing two paints together, and the colour created when glazing washes of the paints over one another. Although this article focuses on the mixing, in a future endeavour we might see what happens with glazes rather than mixes. If we do, we will be sure to share. In the meantime, we wish you joyful watercolor mixing!
