The education in colours is tremendous—in both detail and complexity. If you learn how to distinguish all the colours, to know to what family of colours each belongs, what kind of harmony it can bring about—you can know, it is the same thing. You can keep the memory of the colour as you keep the memory of the form. You want to match all your things... for example, you want to match two things: you want to match a cloak with a skirt or a... well, anything at all... or maybe one kind of cloth with another. Usually you are obliged to take one and then go and compare it with the others; and finally, after many trials, if you are not too clumsy, you finish by finding it. But if you have the training in colour, you look at the colour once and go straight to what matches with it, without any hesitation, because you remember exactly the nature of this colour and go to a colour that can harmonise with it.
