PMU Skin Anatomy & Color Theory 3 — Questions and Answers
Question 1: Which layer of the skin is responsible for producing new skin cells through mitosis?
- Stratum granulosum
- Stratum spinosum
- Stratum basale (Correct answer)
- Stratum lucidum
Correct answer: Stratum basale
The stratum basale (basal layer) contains stem cells and keratinocytes that continuously divide to regenerate the epidermis.
Question 2: Melanocytes are located primarily in which epidermal layer?
- Stratum corneum
- Stratum lucidum
- Stratum basale (Correct answer)
- Stratum granulosum
Correct answer: Stratum basale
Melanocytes reside in the stratum basale and produce melanin, which is transferred to surrounding keratinocytes to determine skin color.
Question 3: What does 'value' refer to in color theory?
- The hue's position on the color wheel
- The lightness or darkness of a color (Correct answer)
- The saturation intensity of a pigment
- The temperature (warm vs cool) of a color
Correct answer: The lightness or darkness of a color
Value describes how light or dark a color is, ranging from white (high value) to black (low value) on a tonal scale.
Question 4: A client with a Fitzpatrick Type V or VI skin type typically has:
- Very fair skin that always burns
- Light skin with occasional tanning
- Olive to brown skin that rarely burns
- Deep brown to dark skin that never burns (Correct answer)
Correct answer: Deep brown to dark skin that never burns
Fitzpatrick Types V and VI describe deeply pigmented skin (brown to dark) that rarely if ever burns and tans very easily.
Question 5: In PMU color theory, 'undertone' most accurately refers to:
- The surface tone visible in bright light
- The subtle hue beneath the skin's surface color (Correct answer)
- The darkest shade in a pigment formula
- The color a pigment fades to after healing
Correct answer: The subtle hue beneath the skin's surface color
Undertone is the subtle hue beneath the skin's primary color (e.g., pink, yellow, or neutral) that influences how pigments appear once healed.
Question 6: The papillary dermis is directly connected to the epidermis via which structure?
- Reticular fibers forming a dense mesh
- Dermal papillae projecting upward into the epidermis (Correct answer)
- Sweat glands running vertically
- Sebaceous glands anchoring the layers
Correct answer: Dermal papillae projecting upward into the epidermis
Dermal papillae are finger-like projections of the papillary dermis that interlock with the epidermis, anchoring the layers together.
Question 7: Which secondary color is created by mixing blue and yellow pigments?
- Violet
- Orange
- Green (Correct answer)
- Brown
Correct answer: Green
Mixing blue and yellow produces green, one of the three secondary colors in the RYB color model.
