Q
Wavelengths
A
Create color and are known as visible light

States that only yellow, red and blue, called primary colors are “pure” colors
7
Q
Primary colors
A
Create all the other colors, cannot be created by mixing colors
8
Q
Secondary colors
A
When 2 primary colors are mixed in varying proportions, they produce the 3 secondary colors. Orange, green and violet
9

16
Q
Characteristics of color
A
Hue
Value

17
Q
Hues
A
Hues are names and abbreviated based on their position on the color wheel
18
Q
Level/value
A
The degree of lightness or darkness of a color, relative to itself and to other colors
19
Q
Level system
A
A numbering system that identifies the lightness or darkness of hair colors in smaller specific increments
20
Q

Lightest hair colors are level 10
Some manufacturers use a 1-12 level system that operates the same way
21
Q

A
Refers to the vividness, brightness or saturation of a color within its own level
22
Q
Color design transformation
A
-visually change or enhance the form of a design
- visually change or enhance the texture of a design
- create a focal point while leading the eye through a design
23
Q
Effects of color on form
A
An all over application of a darker color draws attention to the overall form of a design
24
Q
Color design analysis
A
Color designing is part of a total composition, which also includes the other design elements of form and texture.
25
Designing color includes identifying:
-existing and desired color
- patterns, shapes and techniques that will be used
26
Three levels of observation
Basic, detail, abstract
27
Basic
Identify lightness/darkness and color patterns; visualize first in black and white
28
Detail
Identify remaining color characteristics, such as color family, warmth or coolness, intensity
29
Abstract
Imagine color placement, shapes and patterns for application
30
Sculpted form
Serves as an inspiration for color placement and patterns. Colors can be used to emphasize or de-emphasize the classic shape and texture of a haircut
31
Existing/ desired level
Dark colors visually recede and emphasize shape and shine
Lighter colors create the illusion of more volume
32
Color placement
Zones or zonal patterns subdivide head into multiple areas
Creates a color design with a combination of colors
Depending on the desired effect, some zones may be left natural
33
Examples of areas that can be colored in zones are:
Fringe
Top
Crown
Nape
Perimeter
34
Artistic arrangement patterns for the design elements of:
Form
Texture
Color
35
Melanin
Pigment that gives hair its natural color is known as melanin and is determined through genetic coding
36
3 layers of hair
Cuticle
Cortex
Medulla
37
Eumelanin
A dense concentration will produce very dark hair; a small concentration will produce light hair
38
Pheomelanin
A dense concentration will produce red hair
39
Gray hair
Gray hair is the result of: Melanocyte cells slowing down the production of melanin in the hair strand leading to the gradual and eventually complete loss of colorof
A mixture of non-pigmented hair and pigmented hair on the same head
40
25% gray
More pigmented hair and less non-pigmented hair
41
50% gray
Even mixture of pigmented and non-pigmented hair
42
75% gray
Hair will appear lighter overall
43
Identifying artificial hair color
When a client has had a prior fair color service, you will need to identify the existing artificial color in addition to the natural level and tone
44
5 fields of color
-dark
-medium dark
- medium
-medium light
-light
45
Texture
The degree of coarseness or fineness in the hair fiber
46
Coarse hair
-Resistant to lightening
- may appear to process slightly lighter than intended level when depositing color
47
Medium hair
Has an average response to color products
48
Fine hair
Generally less resistant
May appear to process darker when color is deposited
When lightening or removing pigment, a mild lightener is recommended
49
Resistant porosity
Cuticles are smooth, tightly packed and compact; color absorption may take longer or you may need to apply additional pigment
50
Average porosity
Cuticle is slightly raised, accepts color products easily
51
Extreme porosity
Cuticle is lifting or missing; hair may take color intensely or not be able to hold color, causing it to fade quickly
52
Porosity
The ability of hair to absorb moisture, liquid or chemicals
53
Factors that affect porosity
-sun exposure
- alkaline shampoos
- chemical products
- hair colors
- perms
- relaxers
- heat from hair dryers and curling irons
54
To determine porosity
1. Select a small portion of hair
2. Hold the ends and slide your thumb and forefinger along the strand toward the scalp
3. The more rough the hair feels and the easier the hair back combs, the greater the porosity
55
Nonoxidative color products
Ideal for clients looking to change their existing hair color without commitment
Produce very subtle changes and color enhancements
Keep hair color fresh and vivid between salon visits
56
Nonoxidative color products
-darken, impact shine, add new tones and neutralize unwanted tones
-add pigment but don’t lighten existing hair color
- are not mixed with a developer or oxidant
- used directly out of the bottle or container
57

- create a physical but not chemical change
- deposit color that shampoo out
- temporary and semi

98
What are cotton rolls used for?
Protects client eyes from product drips when positioned around hairlines, used at base in between parting to avoid product seepage during lighter applications, used to perform patch tests
99
Foils of a different color
If you see a different color foil on a client’s head during a highlight or low light service, it often signals that multiple color, products, or formulas, our position within the color design. Color identify where they placed different products by choosing a different color of foil for each formula. This allows them to quickly see the placement pattern as it develops and remind them which color formula to apply next.
