‘Primary

Colours’?

The wrong information—Believed to be fact for several hundred years, widely accepted by the art community and published in many current text books:– The Primary Colours for paint/dyes and inks are Red Yellow and Blue. The secondary colours are Orange, Green and Purple. Complementary colours can be found opposite each other on the colour wheel.
 

The Artists Colour Wheel:

Colour Wheels

 

 

The traditional Artist's colour wheel. In this version the centre has been inverted to show the complements, none of which are correct - colours opposite each other on the wheel should be complements - primaries are Red Yellow and Blue

 

 

 

 

 

 

 

Today's Colour Wheel - correct primaries are Cyan Magenta and Yellow, complements are opposite

 

 

 

The Facts—The relationship between Additive and Subtractive mixing:

 

The Primaries for Light (RGB) and Paint (CMY) are the complements of each other

The Primaries Definition for Paint, Dye and Ink:

  • Cannot be mixed from any two other colours
  • All three mixed equals Black
  • The three colours capable of producing the most other colours

Using Paint Dye and Ink:

Green = Yellow + Cyan
Red = Yellow + Magenta
Blue=Cyan + Magenta

Red cannot be a primary because it can be mixed from Magenta and Yellow, Blue cannot be a primary because it can be mixed from cyan and magenta.

   

The Correct Pigments are: Primary Blue - Cyan PB15:3, Primary Red - Magenta PV19, Primary Yellow PY97.


Maimeri (Italy) is one of only a handful of makers offering artists' watercolour and oil paints labelled ‘primaries’ and one of only two offering paints that actually work: e.g. **Maimeri Blu: superior watercolours, Primary Blue - Cyan 400, Primary Red - Magenta 256, Primary Yellow 116, see Maimeri Blu Watercolours:

http://www.maimeri.it/CGIDEV2P/SIT030.PGM?VARIA=ENAQ001&V4=Watercolours&VX=

These are excellent single pigment paints. Note: Their Puro range of Oils should be as good but to be yet tested and not easily available in Europe.

The only other oil set (not exact primaries and not marked as such but which work in practice) are the **W&N Atiists’ Oil and Watercolour: Cyan Winsor Blue-green shade, Magenta Permanent Rose and Winsor Yellow.

To identify the good form the bad try to find the pigment numbers. e.g. PB15.3. All Artists quality paints will have the pigment numbers on the tube. Avoid any with more than one pigment per paint.
