C33 Color Theory and Color Matching 5

Question 1

What is 'metamerism' in paint color matching?

Accepted Answer

Two colors that match under one light source but differ under another

Answer

Metamerism occurs when two colors appear to match under one type of lighting (e.g., fluorescent) but look different under another (e.g., daylight).

Question 2

A painter needs to lighten a custom mixed color without changing its hue significantly. The best approach is to add:

Accepted Answer

White base or white tint

Answer

Adding white base or white tint increases the value (lightness) of a color while keeping the hue relatively stable.

Question 3

On a standard color wheel, which color is the complement of orange?

Accepted Answer

Blue

Answer

Orange and blue are complementary colors, positioned directly opposite each other on the standard RYB color wheel.

Question 4

When a client specifies a paint color using an LRV (Light Reflectance Value) of 85, the color is:

Accepted Answer

Very light, reflecting most light

Answer

LRV ranges from 0 (absolute black) to 100 (pure white); a value of 85 indicates a very light color that reflects 85% of light.

Question 5

A split-complementary color scheme differs from a complementary scheme because it:

Accepted Answer

Uses the two colors adjacent to the complement instead of the complement itself

Answer

A split-complementary scheme uses a base color plus the two hues on either side of its direct complement, offering contrast with more variety than a simple complementary pair.
