Color Theory and its Applications in Optics Flashcard

Front

What are complementary colors?

Back

Colors that are opposite each other on the color wheel and when mixed, cancel each other out to produce a grayscale color like white or black.

Front

Why do objects that absorb all visible wavelengths appear black?

Back

Because they do not reflect or emit any light in the visible spectrum.

Front

What is the color white in the context of light?

Back

It is the result of mixing all the primary colors of light.

Front

What is the role of a pigment in the coloration of materials?

Back

Pigments absorb specific wavelengths of light, determining which colors are reflected.

Front

What is the primary reason objects appear colored?

Back

They reflect or absorb certain wavelengths of light.

Front

What are primary colors of light?

Back

Red, green, and blue.

Front

What are primary colors of pigments?

Back

Cyan, magenta, and yellow.

Front

What happens when complementary colors are mixed?

Back

They produce a grayscale color, such as white or black.

Front

What is the difference between additive and subtractive color mixing?

Back

Additive mixing combines light colors (RGB), while subtractive mixing combines pigment colors (CMY).

Front

What is the significance of the color wheel?

Back

It visually represents the relationships between colors, including primary, secondary, and complementary colors.
