Watercolour Comparisons 2 - mid yellows

Mid Yellows

I have added all the yellows to my website here.

It is common to have a few yellows in a palette. Traditionally, a cool and a warm yellow, an earth yellow and perhaps a reduced yellow such as Raw Umber. Some artists also add staining or non-staining options, or add an opaque range. I keep a cadmium deep and light in my studio for specific purposes but generally prefer transparent or at least semi-transparent watercolours.

I find I rarely need to use a cool, or green-biased yellow as I am rarely mixing the very bright greens it can make. For me, a good mid yellow that is neither cool nor warm i.e. neither orange-biased nor green-biased is a more useful option than the traditional cadmium or hansa yellow light. This works very well as the only yellow in a limited palette, but is also a nice building colour for an expanded palette.

Aureolin PY40 was the traditional mid-yellow choice, but is not recommended as it goes brown or grey or fades. Originally recommended as a watercolour, now known to be best avoided entirely.

So in my search for a better alternative I have tried a number of other yellows and my favourite is Hansa Yellow Medium by Daniel Smith. Other great choices are Daniel Smith's Quinaphthalone Yellow, Schmincke's Pure Yellow or M.Graham's Azo Yellow for a studio colour since it never really dries due to the honey mixed into the paint. As far as I can work out, all of these are ASTM II pigments, which is acceptable for watercolour.  Cadmium yellows are ASTM I but opaque. 

Here is my mid-yellows page.

These are the mid-yellows I tried. Once again I am searching for colours that re-wet well once dry in the palette, and single pigment colours. I didn't like the Mayan Yellow since it didn't paint smoothly. The Old Holland yellow is a gorgeous colour but, like many Old Holland colours, it dries with a sheen which is frustrating. Note - Winsor Yellow is also a good option, as is Blockx Primary Yellow.

Hansa Yellow Medium or another mid-yellow makes a great triad with Ultramarine and a cool red such as Quinacridone Rose, Quinacridone Magenta or some crimsons - the subject of my next post.

In a larger palette, a warm yellow is convenient for increased mixing options. More on that in Watercolour Comparisons 7.
