Basic Law of Colour (Colour Wheel) in Hair Coloring
The basic law of colour is an important concept in the study of hair coloring in cosmetology. It explains how different colours are related to each other and how they can be mixed to create new shades. The most useful tool for understanding this law is the colour wheel. Hair stylists use the colour wheel to select suitable shades, mix colours correctly, and correct unwanted tones during hair coloring services.
A good understanding of the colour wheel helps cosmetologists achieve professional and balanced hair colour results. It also helps in creating creative and fashionable hair colour styles.
What is a Colour Wheel?
The colour wheel is a circular diagram that shows the relationship between different colours. It is used as a guide in hair coloring to understand how colours interact with each other. The colour wheel contains primary, secondary, and tertiary colours arranged in a circle.
By studying the colour wheel, cosmetologists can easily identify which colours can be mixed together and which colours neutralize each other.
Primary Colours
Primary colours are the basic colours that cannot be created by mixing other colours. These colours form the foundation of all other colours in the colour wheel.
- Red
- Blue
- Yellow
All other colours used in hair coloring are created by combining these primary colours in different proportions.
Secondary Colours
Secondary colours are formed by mixing two primary colours together. These colours appear between the primary colours on the colour wheel.
- Orange – formed by mixing Red and Yellow
- Green – formed by mixing Blue and Yellow
- Violet – formed by mixing Blue and Red
Secondary colours are very important in hair coloring because they help neutralize unwanted tones in the hair.
Tertiary Colours
Tertiary colours are created by mixing a primary colour with a nearby secondary colour. These colours provide additional shades and depth.
- Red-Orange
- Yellow-Orange
- Yellow-Green
- Blue-Green
- Blue-Violet
- Red-Violet
Tertiary colours help hairstylists create natural and customized hair shades.
Complementary Colours
Complementary colours are colours that are opposite each other on the colour wheel. When these colours are mixed together, they cancel or neutralize each other. This principle is very useful in correcting unwanted hair tones.
Examples of complementary colours include:
- Red neutralizes Green
- Blue neutralizes Orange
- Yellow neutralizes Violet
Hair stylists use this rule to correct unwanted colour tones during hair coloring treatments.
Warm and Cool Colours
Colours in the colour wheel are also classified into warm and cool colours.
Warm Colours
- Red
- Orange
- Yellow
Warm colours create bright and vibrant hair shades.
Cool Colours
- Blue
- Green
- Violet
Cool colours produce calm and subtle tones and are often used to balance excessive warmth in hair colour.
