Now, I hate the dichotomy imposed that distinguishes the righteous colorists from the stale tonalist painters. It is, rather, an outlook in my opinion; that is, what aspect of nature moves one painter versus another is a matter of taste. Its personal.
One can either pursue nature, try to reproduce it fully, or alter its appearance in some way. A colorist, at least in the impressionist sense of the word, replaces the actual appearance of nature with his or he subjective style, changing this or that, limiting values and enhancing reflections. Most keep their chromas rather low, like Monet. Others, like Soralla, seem to heighten their chromas a lot more. For me, nature is the utmost guide. But I do change the appearance of things to fit my artistic outlook as well.
That said, the following palette represents the full gamut of paint. (only around 17 pigments ) All, and I mean all miracles, styles, of any outlook can be achieved with this palette since it represents painted color space. Now, its not a palette of convenience. One can add anything else for ease of mixing. But to subtract any of this is to compromise, for the most part, what can be painted.
The Rational Color blog, which I hope will become a separate forum, was created to expand and better understand this range in order to revive art training, obviate nonsense and irrationality in the contemporary art world, and grow the possibilities of oil paint as an expressive and considered medium.
The Gamut of Oil Paint Palette.
Hansa Yellow Medium
Hansa Yellow Light or Cadmium Lemon (Yellow Light) (Note these seem interchangeable)
Pthalo Green (Yellow Shade)
Manganese Blue (Genuine) (occasional and only for one hue)
Alizarin Crimson permanent (the single pigment variety made by Windsor and Newton) or
Pyrrol Ruby (a good replacement for the above )
Burnt Sienna ( for extra chroma in the YR range)
Ivory Black (this is the darkest value available in paint)
Titanium White (this is the lightest value available in paint)
One can see if the following help in rare occasions:
Pthalo Blue (red or green shades)
Phthalo Green (green shade)
The red shade seemed to make little difference when I tried it.
