Goethe’s colour theory differs in a number of respects to Newton’s writings on light. One such distinction lies in Goethe ascribing aesthetic values to the colours of the rainbow, thus: magenta (purpur) and red (rot) are seen as ‘beautiful’ (schön); orange (gelbrot) as ‘noble’ (edel); yellow (gelb) as ‘good’ (gut); green (grün) as ‘useful’ (nützlich); blue (blau) as ‘mean’ or ‘common’ (gemein); and purple (blaurot) or violet (violett) as ‘unnecessary’ (unnöthig). For a while now I have been curious as to why Goethe considered ‘violett’ and ‘blaurot’ to be ‘unnecessary’ and whether this choice of words itself had an effect on the subsequent development of artistic practice. Following some digging around, I ask you to consider the following:

The word ‘magenta’ didn’t exist as a colour term at the time of Goethe’s writing his ‘Theory of Colours’ (original German title’ Zur Farbenlehre’ published in 1810). Indeed the pigment was only invented in 1859 and so the word ‘magenta’ has only been used in more recent translations of the work, as the correct colour to be found next to red but before violet on the colour wheel. In his book the word Goethe used for this colour is ‘purpur’ looking, to English eyes, remarkably like purple. At the other end of the spectrum, Goethe’s words: ‘violett’ and ‘blaurot’ are both close approximations of, yes, purple. To labour the point, on modern colour wheels violet (or purple) and magenta are next to each other, but in Goethe’s wheel, ‘blaurot’ and ‘purpur’ are adjacent. It may be that, due to the quality of pigments available at the time, and lacking the differentiation provided by magenta as a pigment, Goethe saw these colours as actually being too similar, one therefore becoming to him unnecessary.

J M W Turner was heavily influenced by Goethe’s ‘Theory of Colours’, the ideas it promoted having such an effect on the artist that he made reference to the work in the titles of several of his paintings. Turner’s lectures on colour, being delivered around 1827, suggest that he might have been familiar with the book at that time, prior to its English translation in 1840. Interestingly, Turner ignored purple in his own colour wheels produced for these lectures, removing the hue completely from the diagrams and giving half of the spectrum over to yellow in compensation.

Furthermore, you never see purple in any of Turner’s paintings. According to some sources, this is because he simply hated the colour, but what if Turner’s reason for this act of chromicide was due to his incomplete understanding of a yet to be properly translated book, in which the word ‘unnecessary’ took on a greater significance than Goethe had intended? It should also be noted that Turner died seven years before Magenta was first produced.

Did a simple mistranslation affect the entire oeuvre of one of England’s greatest artists? Whatever the reason, thank heavens for that. I too detest purple, with a vehemence brought about by years of teaching art students who, whenever they want to be seen as ‘self-expressive’ use buckets of the stuff usually swirling around in shapes that, diplomatically, can only be described as mystical orifices. Can you imagine a roomful of purple, violet and magenta Turners? The thought makes me feel quite sick.

Why is lemon yellow called ’lemon’ yellow? I have a lemon in front of me and it looks decidedly more like cadmium or chrome yellow in colour. Grapefruits are closer to lemon yellow so why don’t we say ‘grapefruit yellow’? And come to think of it, ginger isn’t ginger, is it?

In his novel ‘The turn of the screw’, Henry James describes the special horror of beholding a ghost in daylight (see entry for Tues 17th Feb). The spirits should belong to the hours of darkness, the time when we should be sleeping, when we let go of the rules of logic. Seeing them beyond these confines adds further to the terror of their encounter. Not only are they there, but they have invaded our territory.

The boundaries of darkness are not the only ones we erect to keep the other world at a safe distance. When we imagine the supernatural, they not only belong to the hours of darkness, but we envision them against a backdrop of ancient buildings, ruins, graveyards, behind the scenes at the fairground, the depths of the woods and the wild moors; places we shouldn’t be. I have wondered if we worship our gods in Churches and temples, perhaps as much to keep them safely out of our everyday lives as to honour them with sacred sites.

The horror of the 1982 film ‘Poltergeist’ while transgressing these boundaries by placing the action within a normal suburban setting, at the last moment gives into convention by revealing the cause of this malevolent infestation: that the housing estate where the story takes place is the site of an old graveyard, and the spirits are, therefore, only reclaiming their land. As the last few remains of the housing development are swallowed up by the ground, paradoxically we know that normality has been restored.

Zombie movies, while more often set in the realm of the everyday, and as much in daylight as at night, still fall back on convention: so what if they can eat our brains or turn us into one of them with a scratch or bite, everyone knows we can finish off the walking dead by shooting them in the head. In this respect Zombie movies are more like alien stories: all of these unknowns have weaknesses we can overcome through courage and technology.

So, what about the idea of suburban ghosts? There are films and stories based on these (e.g. the 70s television series ‘Randall and Hopkirk (deceased)’; ‘Truly Madly Deeply’: ‘The Sixth Sense’; ‘Ghostbusters’…) but in each of these cases the ghost is anything but sinister and, more likely than not, either a comic or tragic figure. Carlos Castaneda perhaps comes closest to the idea of the strangeness of the other existing in our own surroundings when he describes a conversation between himself and Don Juan, the Yaqui sorcerer at the centre of his narratives. While walking through a busy street, Don Juan tells Castaneda that most of the people around him are ghosts and that they walk beside us in every situation. Yet this story still has no real horror in it, perhaps because, if this is the case, how can you be terrified of something that is such a part of normal life?
