Fine hair takes colour faster and can look darker because the melanin granules are grouped:
- A.
More loosely
- B.
More tightly
- C.
More scattered
- D.
Less tightly
Correct Answer
B. More tightlyExplanation
Fine hair takes color faster and can look darker because the melanin granules are grouped more tightly. When the melanin granules are closely packed together, they can absorb and hold onto more color molecules, resulting in a darker appearance. This is why fine hair can appear to be darker when colored compared to thicker hair types.Rate this question:

The ability of the hair to absorb liquids is referred to as:
- A.
Elasticity
- B.
Porosity
- C.
Density
- D.
Diameter
Correct Answer
B. PorosityExplanation
Porosity refers to the ability of hair to absorb liquids. It is a measure of how easily hair can absorb and retain moisture, oils, and other substances. Hair with high porosity tends to absorb liquids quickly and may become dry or damaged easily, while hair with low porosity has difficulty absorbing liquids and may appear resistant to moisture. Understanding the porosity of hair is important for proper hair care and choosing appropriate products that can effectively moisturize and nourish the hair.Rate this question:

When the cuticle of the hair is lifted and the hair is overly porous and absorbs colour quickly, the hair porosity is defined as:
- A.
High
- B.
Medium
- C.
Low
- D.
Even
Correct Answer
A. HighExplanation
When the cuticle of the hair is lifted and the hair is overly porous and absorbs color quickly, it indicates that the hair porosity is high. High porosity means that the hair has gaps and holes in the cuticle, allowing moisture and chemicals to easily enter and exit the hair shaft. This can result in hair that is prone to frizz, tangles easily, and has difficulty retaining moisture.Rate this question:

The system used for understanding colour relationships is is the:
- A.
Colour wheel
- B.
Law of colour
- C.
Level system
- D.
Colour system
Correct Answer
B. Law of colourExplanation
The correct answer is "law of colour" because the term "law of colour" refers to the principles and theories that govern the relationships between different colors. It is a system or set of rules that helps in understanding how colors interact with each other, how they can be combined or contrasted to create different effects, and how they can be used in various art forms and design applications. The color wheel is a visual representation of the law of color, which organizes colors in a circular format to show their relationships and harmonies. The other options, such as "level system" and "color system," are not specific terms related to understanding color relationships.Rate this question:

Fundamental or pure colours that cannot be achieved from a mixture are:
- A.
Warm colours
- B.
Base colours
- C.
Primary colours
- D.
Secondary colours
Correct Answer
C. Primary coloursExplanation
Primary colors are fundamental or pure colors that cannot be achieved from a mixture of other colors. They are considered the building blocks of all other colors. Mixing primary colors together can create a wide range of secondary and tertiary colors, but primary colors themselves cannot be created by mixing other colors. Therefore, primary colors are the correct answer to the question.Rate this question:

The primary colour that brings depth or darkness to any colour is:
- A.
Red
- B.
Yellow
- C.
Blue
- D.
Green
Correct Answer
C. BlueExplanation
Blue is the correct answer because it is a primary color that has the ability to bring depth or darkness to any other color. When blue is added to a color, it creates a darker or more intense shade of that color. This is because blue is a cool color that has a lower intensity compared to warm colors like red or yellow. Adding blue to a color can create shadows, give a sense of depth, or create a darker tone, making it the primary color that brings depth or darkness to any color.Rate this question:

When all three primary colours are present in equal proportions, the resulting colour is:
- A.
Brown
- B.
Black
- C.
Green
- D.
Orange
Correct Answer
B. BlackExplanation
When all three primary colors (red, blue, and yellow) are present in equal proportions, they cancel each other out and create black. This is because each primary color absorbs one of the other primary colors. For example, red absorbs green, blue absorbs orange, and yellow absorbs purple. When all three primary colors are present, they absorb each other, leaving no color to be reflected, resulting in black.Rate this question:

A colour obtained by mixing equal parts of a secondary colour and its neighbouring primary colour on the colour wheel is a:
- A.
Complementary colour
- B.
Pigmented colour
- C.
Tertiary colour
- D.
Base colour
Correct Answer
C. Tertiary colourExplanation
When equal parts of a secondary color and its neighboring primary color are mixed, it creates a tertiary color. Tertiary colors are formed by combining a primary color with a secondary color. The primary colors are red, blue, and yellow, while the secondary colors are orange, green, and purple. Mixing equal parts of a secondary color (e.g., orange) and its neighboring primary color (e.g., red or yellow) will result in a tertiary color (e.g., red-orange or yellow-orange). Therefore, the correct answer is tertiary color.Rate this question:

Colours that can look deeper than their actual level are:
- A.
Natural tones
- B.
Cool tones
- C.
Warm tones
- D.
Lightest tones
Correct Answer
B. Cool tonesExplanation
Cool tones, such as blues and purples, can create an optical illusion that makes them appear deeper than their actual level. This is because cool tones have a receding effect, causing them to appear farther away and creating a sense of depth. On the other hand, warm tones, like reds and oranges, tend to appear more vibrant and closer, while natural and lightest tones do not have the same depth-enhancing effect as cool tones.Rate this question:

Neutral base colours are often used to cover:
- A.
Grey hair
- B.
Red tones
- C.
Gold tones
- D.
Ash tones
Correct Answer
A. Grey hairExplanation
Neutral base colours are often used to cover grey hair because they help to blend the grey strands with the natural hair color, creating a more cohesive and uniform look. Neutral base colors have equal parts of warm and cool tones, making them suitable for covering grey hair, which can have a mix of both warm and cool undertones. This helps to achieve a natural-looking result and provides good coverage for grey hair.Rate this question:

Primary and secondary colours that are positioned opposite each other on the colour wheel are:
- A.
Complementary colours
- B.
Contrasting colours
- C.
Permanent colours
- D.
Tertiary colours
Correct Answer
A. Complementary coloursExplanation
Complementary colors are positioned opposite each other on the color wheel. When these colors are combined, they create a high contrast and enhance each other's intensity. This creates a visually pleasing effect and is often used in design and art to create balance and harmony. Contrasting colors, on the other hand, may not necessarily be positioned opposite each other on the color wheel and may not create the same harmonious effect when combined. Permanent colors and tertiary colors are not directly related to the concept of colors being positioned opposite each other on the color wheel.Rate this question:

The process that lightens hair and deposits colour in one application is:
- A.
Deposit-only colour
- B.
Semipermanent colour
- C.
Single-process hair colouring
- D.
Double-process hair colouring
Correct Answer
C. Single-process hair colouringExplanation
Single-process hair coloring refers to a hair coloring technique where both lightening and depositing color are achieved in one application. This process involves using a permanent hair dye that lightens the natural hair color and deposits the desired color at the same time. It is a convenient and time-saving method compared to double-process hair coloring, which requires separate steps for lightening and coloring the hair. Deposit-only color and semi-permanent color do not involve the lightening process, making single-process hair coloring the correct answer.Rate this question:
