Warm and cold colours

Colour theory classifies all shades of colours: warm colours convey joy, passion, sensuality, whilst cold colours are associated with sweetness and rest.

Cold colours are: green, blue, indigo and violet. Warm colours are: red, orange and yellow.

Cold colours are linked to quietness, sweetness, rest, contemplation, sadness and different shades of these frames of mind. Warm colours, on the contrary are exciting, they convey joy, strength, power, energy, passion.

In the natural environment we can find the same analogies: blood is red, flames are orange and the sun is yellow and they are all warm. Water and plants are blue and green and they are relaxing. If we get into a yellow room, we will feel more cheerful and lively than if we enter a blue or green room, which conveys tranquillity.

And there is another distinction:

  • Red, orange and yellow (warm colours) have a positive radiation;
  • Blue, violet and indigo (cold colours) have a negative radiation;
  • Green is both negative and positive and many experts say that it is the link between the two categories.

The colour theory was postulated for the first time in the first decades of the Twentieth century by Turenne, renowned scientist and engineer at the central school of Paris, the academic institute attended by the country’s elite. Not only was he a lead scientist but he also was the first to study scientifically a few phenomena of colours, about which the other scientists of that time were sceptical.
