CCE Lighting & Material Interactions 2

Question 1

A fabric appears vibrant under tungsten lighting but dull under fluorescent. This phenomenon is best described as:

Accepted Answer

Metamerism

Answer

Metamerism occurs when two colors match under one light source but differ under another due to different spectral reflectance curves.

Question 2

Which material finish would show the greatest variation in apparent color when viewed at different angles?

Accepted Answer

Pearlescent automotive finish

Answer

Pearlescent finishes contain mica or interference pigments that shift color with viewing angle due to thin-film interference effects.

Question 3

The Color Rendering Index (CRI) measures a light source's ability to:

Accepted Answer

Accurately render object colors compared to a reference illuminant

Answer

CRI compares how faithfully a light source renders 8 standard test color samples relative to a reference illuminant of the same color temperature.

Question 4

A north-facing room receives predominantly which type of daylight, and how does it affect color perception?

Accepted Answer

Cool blue-shifted light that enhances blues and grays

Answer

North-facing rooms receive indirect, blue-shifted skylight (higher CCT) that tends to make colors appear cooler and slightly desaturated in warmer hues.

Question 5

Velvet fabric often appears darker than other textiles of the same dye lot. The primary reason is:

Accepted Answer

The pile structure causes multiple internal light reflections that trap light

Answer

The upright pile of velvet causes light to bounce repeatedly within the fiber structure, increasing absorption and producing a deeper, darker apparent color.
