Families of colours


[Translation: Anne Clerget]
French text

 

 

 

[Recommended reading :
The colours in the French language, Pourpre.com]

 

The colours we identify today are still arbitrary categories, with vague limits.

We thought for a long time that the first colour chart had been created during the XXth century. For example, according to  Kevin Mac Cloud, it was the Royal   Horticultural Society Handbook, dated from 1939, and meant to make an inventory of floral nuances.

Summary

Distinction of colours

Colour and eye

The colour exists because of the pigment and the lighting

In fact, it appeared recently that the first colour chart could be more ancient. It could date from the XVIIth century and its author is supposed to have been an astronomer, Aron Sigfried Forius. About this read, The colour charts on Pourpre.com and Curiosities on the same website.

Nevertheless, if Kevin Mac Cloud, like most of the authors, made a slight mistake in the dating, we must give him credit for having described the unquestionable reality of a dimension way more determining: "In reality, the old shades were extremely variable, since the decorators made their blends on the premises."

Here is the practical reality, reality of the decorator as of the artist because what counts last is the verdict of the palette !

 

But let us go back to our initial topic. The accuracy or the inaccuracy of a colour as well as its belonging to a precise "family" are relatively new concepts. Whereas modern times taught us to use chromatic classifications which seem to have always existed, let us question ourselves about our conceptual heritage for a moment.

Different peoples – including western peoples – distinguished only late

in their languages the blue from the green, or assimilated violet to black or dark green to grey,  for example. Besides, it is maybe quite right to advance that value prevails often upon colour in our perception, and that is still particularly true in the field of composition. It may explain the slowness of mankind to identify colours rightfully. However, a lot of ideological a priori (political, religious) contributed greatly to some confusions, or delays.

Traces of these misguided thoughts are handed over from generation to generation, doubtlessly because their origin is historical, and also because they result from former power conflicts badly elucidated or healed.

This is not for nothing that for a very long time, a priori rejections and (sometimes violently) libellous remarks pepper the "hearsay" still circulating in the world of painting – just like, at certain periods, in the world of religion or politics - about such or such pigment, such or such colour family (for example, read the introduction of the article about yellows).

This is the occasion to say that always and from any point of view, colour needs light, despite the advancements.

 

 

    Distinction of colours

 

According to an information (not yet confirmed), our visual system   would have preferential aptitudes to perceive hues of green, yellow and brown, but would be less effective with blue, and especially with violet, red and orange which are less present in our natural environment. Any further scientific information on this subject is welcome.

From time to time, such or such master declares that  "the blue gets away", thinking to report an almost universal value (the distant in the nature, on our planet, is bluish; the sky itself is blue). Many painters have shown many times that the impression of distance proceeds in the first place from the contrast, thus from a relative fact, and not from a unique, immutable chromatic reference; A colour truly reveals itself only in the presence of other colours. Just like in physics, everything is relative.

The artists who work on the image(photographs, film or video directors, painters) do not ignore that a black juxtaposed to a green will look reddish, that an ultramarine placed close to a violet will look warmer than beside a cobalt blue. The eyes try to separate shades by exaggerating them.

Therefore, it is not very surprising that humans waited such a long time before making the first colour charts: it was so easy to get lost. It was much easier to hang onto families to which such or such virtue or symbolic signification was ascribed.

 

    Colour and eye

 

Eyes are  the second half of the concept we call "colour". Claude Monet, operated for cataract, is supposed to have modified his palette after the surgery. This is not an isolated case.

While, very often, we seek for symbols in the choice of colours, we forget that because of a simple problem of cristalline lens – which can be solved now with a ten minutes surgery -, a painter can perceive red and yellow ten times better than blue, purple or green !

Cruel and humiliating reality : it reminds us that only the perception of the differences of value (luminosity) is approximately universal... when it is accessible.

 

    The colour exists because of the pigment and the lighting

 

What painters and visual artists manipulate, are real pigments and not some theoretical spectrum classified into theoretical categories.

Each jar of pigment, each flake, each grain of pigment, is a unique kind. Each of the coloured substances we manipulate has a story and has not been waiting for us to exist under multiple forms. A trivial bottle of iron oxide contains atoms that saw galaxies, worlds uprise. The instant look of a radiation (colour, light) sent back by a substance is often only a part of the criterias conditioning the painter’s choices.

Whatever the classification of colours : the aspect, the origin, the fabrication, the history of the pigment will govern the artist’s preference, which is not always reasonable. There are genuine passionate relationships between artists and pigments. They owe more to feelings and sensitivity than to classifications and tradition, all the more as lots of pigments have been created during these last centuries.

Moreover and above all, the colour of a pigment is not an immutable fact. It depends entirely of the light, its intensity, its chromatism and of the viewer’s eye. The colour is the encounter between a pigmentary substance,  a lighting and a viewer.

 

However, in this section we present you  a chromatic classification, hoping simply  that it will favour savoury encounters.
