In addition, we will also introduce some basics regarding colors so that we can more easily discuss their application in restaurant interior design.
Contrasts in every sense (dark-light, warm-cold) are mostly interesting. The best example of a contrast is black-white, which is always attractive. But when we talk about pairing colors, we must be careful. We can combine them, but they must not be of the same intensity, i.e. they must not be pure colors.
We can use pure colors as details. In any other way they would be too aggressive and unpleasant to your customers. If your wish is to shock and send out a message, then everything is allowed and you are entering a sphere of art. However, if you are not an artist, you will probably get a poor result.
If you wish to visually expand a certain room, use cold or light color tones with minimal contrasts. If you wish to narrow the space, use warm colors in darker shades and bigger contrasts.
The ceiling will appear lower if it is darker or warmer then the walls, and higher if you apply the opposite effect. In any case, surface that is to affect the size of the space is always to be darker or warmer shade than the remaining walls.
Colors also have a strong psychological effect on us. Red, orange and yellow stimulate energy and good mood, while green, blue and purple are calming.
More about colors
Color is a reaction of light receptors in our eyes to the external spectrum of light.
The external light is white; therefore white is an achromatic color. Black and grey are also achromatic colors.
The spectrum was discovered by Isaak Newton in 1676. His conception includes seven colors: red, orange, yellow, green, blue, indigo and violet.
Color is the perception of a certain frequency range, from 400 to 800 billion Hz. Before red, there is infrared, invisible to us, and before violet, there is ultraviolet.
Children are taught there are six colors – three primary and three secondary colors. All colors can be created by mixing the three primary colors, red, yellow and blue.
By mixing primary colors, we get secondary colors.
blue + yellow = green
red + yellow = orange
blue + red = violet
By mixing primary and secondary colors, we get tertiary colors, for example, red-orange or orange-red. When we arrange primary, secondary and tertiary colors in a circle, we get the so called Ostwald color-circle.
Colors that are not in the spectrum are achromatic colors: white, black and grey. By adding these colors to chromatic colors, we get tones of chromatic colors. Tone is the added light to a color, therefore we have light blue, dark blue, darker blue, until black is reached.
It is important to mention that every color, without adding white or black, already has its own light. Yellow is the lightest, followed by orange, then red and green, blue and in the end violet as the darkest.
Warm and cold colors
Colors can also be divided into warm and cold colors. If we look at the Ostwald circle, we will notice that warm colors (red, yellow and orange) are on one side and cold colors (blue, green and violet) are on the other side of the circle. By adding a warm color to a cold one, we can make it warmer. Another useful fact is that warm colors visually expand and come closer while cold colors contract and move away from the viewer.
We should also mention complementary pairs of colors. These colors are in a complementary contrast and are derived when one primary color is placed next to one secondary color that is made up of the other two primary colors. Complementary pairs are placed one opposite the other in the Ostwald circle.
They are: red-green, orange-blue, yellow-violet.
