Rublev Eighteenth Century Watercolor Palette

Browsing the Natural Pigments website recently, I noticed that they have made considerable changes to their "18th Century Watercolor Palette" product since I purchased it in May, 2008.

The lists below compare the old and new paint choices:

2008 Palette 2010 Palette
Lazurite (B29)
Nicosia Green Earth (G23)
Verona Green Earth (G23)
Italian Yellow Earth (Y43)
Gold Ochre (Y43)
Italian Dark Ochre (Y43)
Venetian Red (R102)
Ercolano Red (R102)
Italian Burnt Sienna (Br7)
Cyprus Burnt Umber Warm (Br7)
French Raw Umber (Br7)
German Vine Black (Bk8)
Prussian Blue (B27)
Green Earth (G23)
Olive Green (G23)
Yellow Ochre (Y43)
Gamboge (NY24)
Vermilion (R106)
Madder Lake (NR9)
Indian Red (R102)
Burnt Sienna (Br7)
Burnt Umber (Br7)
Payne's Grey (Bk9)
Bone Black (Bk9)

Because I do not have the updated palette on hand, I can only approximate the paint choices based on my own knowledge. Rublev make three Burnt Umber paints, and two Burnt Sienna paints (all of which I own) - so while I can make an educated guess, it is still a guess.  With a nod to Bruce MacEvoy, I have provided two small diagrams to help visualise the paint differences and their approximate place on the colour wheel:

C18th Palette, 2010
As you can see, this is quite a radical shift in terms of palette colour and mixing range.  The main improvement of the new palette is that the paints chosen are better spaced within the colour wheel.  The two yellow paints were originally quite interchangeable unless applied full strength, and their mixing capability was similar. The addition of Gamboge (fugitive NY24) should make for sweeter yellow tints.  With the introduction of Madder Lake (fugitive NR9) and Prussian Blue, purple becomes possible - the previous mixture of Lazurite and Venetian Red could only produce a greyed violet-brown colour. However, the loss of subtle Lazurite is a sad one, as it is a lovely and highly textural paint.  Gone are Ercolano and Venetian Red, instead we have Indian Red (a favourite paint of mine) and bright Vermilion - the pretty but toxic PR106.

(A comparison image of the updated C18th Palette will be added shortly.) 

I have tested almost every watercolour paint in the Rublev line, and all have delightful textural properties.  I use these paints mostly for small works or field sketches, as the paints are best applied and then left alone. Re-wetting them and brushing over them lifts them and destroys the texture.  The updated palette introduces mostly staining paints - this will reduce lifting with the brush in mixtures and help to make the paints a little easier to use.  While the updated choices are a good introduction to historical paint, I do wish strident Prussian Blue was not the only blue choice.

Rublev Nineteenth Century Palette


Earlier this year I treated myself to a Rublev "19th Century Watercolor Palette".  The main attraction for me was the presence of real Vermilion (Mercuric Sulfide PR106) and a lead yellow, Chrome Yellow Primrose (Lead Chromate PY34). While both of these toxic historical pigments are readily replaced with a cadmium paint, I was curious about the originals all the same.

As you can see, this is a palette devoid of green paint. This poses no problem because a variety of attractive greens can be mixed here, especially with vibrant Primrose.

Because colour wheels are interesting, below is a diagram which shows the approximate location of these well-spaced paints on the colour wheel:


From the website:

"Due to the large particles of this color, we recommend using this watercolor only with rough watercolor paper or with additional watercolor medium to aid the large particles to adhere to the paper."
This is good advice. These paints disturb easily and do not accept re-work, put it down and leave it. :)

Pigments and Palettes

Later this month I'm attending a one-day oil painting workshop given by a local artist.  It's a beginner's class, but I'll take anything to do with oil painting right now. (I'm finding it is the most convenient medium for me to work with now that I am home with my first baby - I can come back to a piece hours later and just pick up where I left off.)

The workshop will be focused around creating paintings with a limited "primary triad" palette consisting of only cyan, magenta, and yellow.  The instructor has recommended the following (Art Spectrum brand):
  • Cadmium Yellow (PY35)
  • Permanent Magenta (PV19, PV23)
  • Phthalo Blue (PB15:3, PW21)
I will be using my M. Graham & Co. paints, plus Michael Harding's Magenta - PR122 is too much of a glorious pigment to go unused. :)

Rublev Eighteenth Century Palette

Here is a scan of a watercolour set from Natural Pigments. This is the rather lovely "18th Century Palette": (Click to enlarge!)


I have tested almost every watercolour paint in the Rublev line, and all have delightful textural properties.  I use these paints mostly for small works or field sketches, as the paints are best applied and then left alone. Re-wetting them and brushing over them lifts them and destroys the texture.

(Update: 2013: Over time, some paints became unusable, and would no longer produce colour when re-wetted, even if soaked. Vivianite (Blue Ocher) was of much interest to me but is now just an inert lump which does not respond to water.)
