1. Adherence to the Color Wheel
The color wheel was invented by the genius scientist Isaac Newton, who broke down white light into a spectrum of 7 colors with wavelengths ranging from 0.75 micrometers (red light) to 0.38 micrometers (violet light). These 7 colors, commonly known as the 7 colors of the rainbow, include: red, orange, yellow, green, blue, indigo, violet.
According to current architectural documents, the color wheel can easily be divided into 4 basic groups:
- Group 1 colors (Primary colors): red, yellow, blue are the primary colors that when mixed together create other colors. When combining any 2 colors from group 1, a color from group 2 is created
- Group 2 colors (Secondary colors): orange, green, purple are secondary colors. Group 2 colors mixed with Group 1 colors will create Group 3 colors
- Group 3 colors (Intermediate colors): these are intermediate shades such as orange-red, orange-yellow, yellow-green, blue-purple, red-purple…. are intermediate colors.
- Group 4 colors (Complementary colors): complementary colors consist of pairs of colors with contrasting degrees such as Red – Green, Orange – Blue, Yellow – Purple…but lighter in intensity. Complementary colors placed next to each other often enhance each other moderately but cause eye strain like other contrasting color pairs. Although they are essentially contrasting color pairs, the reduced intensity makes viewers impressed without causing eye strain.

2. Use Level 4 Contrasting Colors: Warm and Cool
Level 4 colors consist of Warm Tone colors such as red, orange, yellow, brown for a warm, visually stimulating feeling, making the space appear smaller in size. Cool tone colors are blues, greens... creating a cool, refreshing feeling and are also the most chosen color range. Meanwhile, subdued, muted shades require careful color coordination with various other colors, so they are also selective. But if you know how to coordinate colors, these tones will make the design style of the house more impressive. The principle of contrasting colors is to combine a dark color with a light color. You can combine white or black clothing with red, orange, yellow, purple; nude color, cream color with pink, green or sky blue... With this combination, the outfit will become much more elegant and sophisticated. Contrasting colors can be coordinated between different areas; between furniture pieces or between wall paint and furniture.


3. Colors Need to Suit Age, Gender, Personality
For individuals of different ages, genders, and personalities, different paint color tones will be suitable. Determining these factors is a very important step - this is also the first factor that architects and interior designers often ask their clients. From there, you can draw experiences for your own decoration. If you are young, female, and have a lively personality, you should choose warm, hot colors like red, coral, yellow, orange, peach. On the contrary, for young, calm males, choosing cool-toned paint colors like blue, navy blue would be suitable. For girls, choose cute shapes, sweet colors; boys will love nature, cosmic shapes... Or girls often want warm spaces, while boys prefer simplicity, masculine black tones, for example...


4. Analogous Colors
The method of this principle is to use a color scheme with different shades continuously on the color wheel. These are called analogous colors. When these colors are combined, they will give your home an impressive and stylish overall look by changing the different shades of colors. The various transitions of light and dark shades of the same color tone do not diminish uniqueness but still exude harmony, lightness, sophistication, and creativity for your favorite paint color.


5. Neutral Color Coordination
The advantage of using paint with neutral tones is that you can easily combine it with any other color or with various decorative items, especially bold colors. This coordination method helps your home not to appear flashy or confusing but much more elegant. Neutral colors are a popular choice for wall paint coordination in home decoration. Neutral color tones often used are gray, beige, white, skin color, brown, black, gray, cream... This color coordination method is the safest if you are not familiar with architectural design but still want to design your home yourself and they are suitable for every type of home, every space in the house.
