● The spectre of the white light consists of 7 colors of the rainbow: purple, indigo, blue, green, yellow, orange-coloured, red. Every color possesses its own wavelength. → Our brain looks for naturally the balance and the harmony! The eye runs out on the green, to compensate for the brain look for the complementary. Red / blue = purple say magenta, eye so makes his own mixtures ! He restores the missing color; the green creates the red; the blue creates the yellow (successive said contrasts). ● Mixture, chromatic vocabulary : - Colors can be complementary 2 by 2. They are set then diametrically on the circle. The orangy colour is the complementary of the blue. The purple is the complementary of the yellow. - The primary colors are also said fundamental or elementary, in subtractive system, for the painters: Red - Yellow - Blue. - Secondary colors: some examples Red + Yellow = Orange;  Yellow + Blue = Green;  Blue + Red = Purple - 1 primary color + 1 secondary color: red + orange = orange-red; yellow + orange = yellow-orange;   blue + green = blue-green;   red + purple = purplish red

● Let us speak about the same language!
The tint indicates that is the color: red, orange-coloured, yellow, green, blue, purple, white, black, grey, brown, pink...
The nuance is each of the degrees of the same color, there are thousands, example of the red there: vermilion, Cerise, Blood of ox, Carmine...
The tone indicates the modification of a color in its value: clearly, dark, bright, dark, dark, average, lively, opaque, transparent...
tint: red  nuance: vermilion  tone: bright   -   tint: green  nuance: celadon  tone: transparent.
Examples: purple of opaque Parma; lemon yellow clearly; red sinks Bordeaux; golden yellow darkened; average Cobalt blue...
Neutrals: grey, black, white, brown, beige. Neutrals balance a decoration and are very influenced by the neighbouring colors especially if these last ones are frank and in great quantities.
The gradation: a progressive combination, a passage between two colors, two values. Example: red → Fuchsia → Purple plum.
The cameo: not progressive combination between close colors, stemming from the same range.
Example of greens: emerald, English, of Paris, khaki, greenish yellow, mignonette, foam, olive, lemon, lime tree, ivy, lettuce, meadow, lawn, pine, almond, pea, apple, eucalyptus, leek, spinach, watercress, pistachio nut, chartreuse, spring = numerous nuances!

● It is necessary of the method / marks: - The color is connected to a support which modifies the perception! Paint, lime, concrete... - As well as clear distinction between matt, sheen and diamonds: the light touches a smooth surface, it bounces on the brilliant,   it becomes blurred in the softness, it hangs on to the harshness, it becomes iridescent in silks, it dozes off in the somber … - Choose! Thus learn to give up … - The feelings engendered by our subjectivity dictate unconsciously an aversion or an attraction towards a color. - A room is made of 6 to consider sets. - The clear tones put off a wall and the dark tones move closer to them. - Every volume was colored, every motive are so many graphic lines to be made readable. - The same color on the ground gives an impression of unit and peace. ● Parameters to be taken into account: - The volumes, the lines, the materials, the lights: natural / artificial     + The color is clear + it reflects the light. + She is dark, less she reflects the light. - Cold tints: rather reserved for rooms presentations in the sun due south; - Warm tints esteemed the North to compensate.

● Axes of reflections for a harmonious decoration
A - Choose an atmosphere: agreements with close tones (gradations, cameo) or choice of a contrast (opposite colors).
B - Choice of a color range:
      1 - Agreement from 3 to 7 tints, to take into account existing masses such furniture, sofa!
      2 - Define the surface occupied by every color; to specify the dominant, it is + large surface, and the tonic generally + small surface.
      3 - The intensity of the dominant color is decreased or broken or pulled down or in colored grey, to exploit the other colors.
      4 - Observe all the contrasts: colors, materials, lines
      5 - Choose the materials of finish: matt, satin, shine? According to the material, the color is not revealed in the same way = to make samples!
      6 - Optimize the set with different light sources, the lighting:
           → Natural lighting: variation according to the hour, according to season, according to the orientation of rooms…
           → Artificial lighting: variation according to quality and the quantity, the temperature of the lighting + its coefficient of depiction of colors ( IRC)
           = Our old electric bulbs gave a light with yellow color dominant
           = The compact fluorescent bulbs limit the yellow, the red, the orangy + give of the reflection to the blue, black, white and green
           = The halogen returns a light which is close to that natural
           = Fluorescent lamps (said wrongly neon) + compact fluorescent lamps give a rather bluish light
           Électroluminescence: electronic domain, production of electron: led, oled.
           Mercury = blue - used warm country… Sodium = yellow golden orange-coloured - used cold country… Xenon = gets closer to the pure white.
