Color
      Yellow
          Keen lemon-yellow hurts the eye in time as a prolonged and shrill trumpet-note the ear.
          One might say that keen yellow looks sour, because it recalls the taste of a lemon.
          it would be hard to find anyone who would try to express bright yellow in the bass notes
          Everyone knows that yellow, orange, and red suggest ideas of joy and plenty.
          Generally speaking, warmth or cold in a colour means an approach respectively to yellow or to blue.
          in the yellow a spreading movement out from the centre, and a noticeable approach to the spectator.
          The intensification of the yellow increases the painful shrillness of its note
          Yellow is the typically earthly colour. It can never have profound meaning.
          there can never be a dark-coloured yellow.
          Yellow has a disturbing influence, and reveals in the colour an insistent, aggressive character
      Blue         
        When it sinks almost to black, it echoes a grief that is hardly human.
        As an echo of grief violet stand to blue as does green in its production of rest.
        When it rises towards white, a movement little suited to it, its appeal to men grows weaker and more distant. 
        In music a light blue is like a flute, a darker blue a cello; darker a thunderous double bass; and darkest blue-an organ.
        A well-balanced mixture of blue and yellow produces green.
        It may be paralleled in human nature, with madness with violent raving lunacy.
        physical movements (1) of retreat from the spectator, (2) of turning in upon its own centre. 
        The inclination of blue to depth is so strong that its inner appeal is stronger when its shade is deeper. 
        Blue is the typical heavenly colour.
      White
        White, therefore, has this harmony of silence.
        White has the appeal of the nothingness that is before birth, of the world in the ice age.
        Not without reason is white taken as symbolizing joy and spotless purity.
      Black
        A totally dead silence, on the other hand, a silence with no possibilities, has the inner harmony of black.
        Black is something burnt out, like the ashes of a funeral pyre, something motionless like a corpse. 
        The silence of black is the silence of death. 
        Outwardly black is the colour with least harmony of all, a kind of neutral background against which the minutest shades of other colours stand clearly forward.
      Red
       Red
        red may cause a sensation analogous to that caused by flame, because red is the colour of flame. 
        A warm red will prove exciting, another shade of red will cause pain or disgust through association with running blood.
        They have shown that red light stimulates and excites the heart
        Everyone knows that yellow, orange, and red suggest ideas of joy and plenty
        when the word red is heard, the colour is evoked without definite boundaries
        exercises at once a definite and an indefinite impression on the soul, and produces spiritual harmony
        The unbounded warmth of red rings inwardly with a determined and powerful intensity 
        By a skillful use of it in its different shades, its fundamental tone may be made warm or cold.
        no colour has so extensive a scale of varieties as red.
        Light warm red gives a feeling of strength, vigour, determination, triumph. 
        In music, it is a sound of trumpets, strong, harsh, and ringing.
        Cool red (madder) like any other fundamentally cold colour, can be deepened.the inward glow increases, the active element gradually disappears.
        A cold, light red contains a very distinct bodily or material element, but it is always pure, like the fresh beauty of the face of a young girl. 
       The singing notes of a violin express this exactly in music.
       Orange
         Warm red, intensified by a suitable yellow, is orange. 
         This blend brings red almost to the point of spreading out towards the spectator. 
         the element of red is always sufficiently strong to keep the colour from flippancy.
         A red sky suggests to us sunset, or fire, and has a consequent effect upon us—either of splendour or menace. 
       Vermillion
         Vermilion has the charm of flame, which has always attracted human beings.
         Vermilion rings dull and muddy against white, but against black with clear strength.
         Vermilion is a red with a feeling of sharpness, like glowing steel, which can be cooled by water. 
         Vermilion is quenched by blue, for it can support no mixture with a cold colour.
         The vermilion now rings like a great trumpet, or thunders like a drum.
      Gray
	Similarly a mixture of black and white produces gray, which is motionless and spiritually very similar to green.
	In gray there is no possibility of movement, because gray consists of two colours that have no active force.
	A blend of black and white produces gray which, as has been said, is silent and motionless, its restfulness having none of the potential activity of green. 
        A similar gray is produced by a mixture of green and red, a spiritual blend of passivity and glowing warmth.
      Green
        Opticians agree that green is the  most restful color in existence; pictures painted in green tend to be wearisome-passive.
        green is the ‘bourgeoisie’-self-satisfied, immovable, narrow. 
        It is the colour of summer, the period when nature is resting from the storms of winter and the productive energy of spring
