Colors are the cornerstones of the graphic design. Graphic designers are well aware that minor changes in color made at an imperceptible location will influence the design process.

Here, the expertise and imagination of the graphic designer are significant. Luckily, the ever-evolving color theory learned from previous artists now shines light on the direction of contemporary graphic designers and graphic design service providers. 

What's the Theory of Color? 

Color theory is a set of rules and techniques that have been created for use in graphic design or art. Color theory proposes a number of color harmonies to make the designer's task simpler. Color harmonies are, as the name implies, harmonious, actually, technically harmonious. 

Each color harmony is regulated by its own rules. In this sense, the color harmonies can be contrasted with the modes in music and the measure in poetry and this harmony quite critical in terms of providing effective graphic design services.

Color Harmonies 

Complementary colors: two colors facing each other in the color circle are complementary. Supplements widely known: red-green, yellow-purple, blue-orange. 

Analog colors: produce an analog unity with the adjacent colors in the color wheel: blue-green-yellow, yellow-orange-red, navy-blue-purple, etc. 

Three-corner colors: the three colors to be determined at equal intervals in the circle are in harmony. Like green-orange-blue, red-yellow-blue. 

Discreet complementary colours: similar to complementary colours. Instead of taking a single complementary color for each color, two neighboring colors are used. It's like green-pink-orange. 

Four-corner colors: four equal distance points in this harmony are subject to the same rules for three-corners. 

Monochromatic colors: is the balance achieved by changing the saturation and/or the lightness of the hue defined by the color circle. This kind of peace can be created with blue, light blue, sky blue, and ice blue.

The Place of Color in Human Psychology 

When our visual perception is activated by an object, our mind is experiencing a conscious or unconscious process. Another feature of color theory is that shades, which play an important role in this process, have an indirect influence on human psychology. 

Below colors we have mentioned some colors and its expected results: 

Passion, passion, anticipation, desire to act: it is assumed that these emotions can be produced in an equivalent color harmony with red color  

Calmness, peace of mind: green and its variants, soft blue colors. Around the same time, fitness, life, and so on. It is a color that is mostly favored by health establishments because it often promotes this kind of thinking. 

Trust: blue and the variants. Many of the blue shades can be used in the branding examples of technology companies. 

Strength, perception of exclusivity, authority: black. You can see black in most businesses that boast of being "prestigious" These patterns, which are rendered simply and elegantly, are often accompanied by a golden yellow hue. 

It should be remembered, though, that these are generalizations that have been made roughly. While it is often useful to base human psychology on such assumptions, it can not necessarily achieve the desired outcome. 

For example, in a city exposed to a tsunami catastrophe, it might not be a smart option to expect the blue color to offer trust. Hence, when offering graphic design services, it is especially important to behave in line with the philosophy of colors and their meaning and to add value to practice. 

Picking a nice color is as important as choosing a nice logo design, business location. Colors have many effects on the human eyes so do choose your colors wisely.
