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

    Answer: Metamerism

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

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

    Answer: Pearlescent automotive finish

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

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

    Answer: Accurately render object colors compared to a reference illuminant

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

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

    Answer: Cool blue-shifted light that enhances blues and grays

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

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

    Answer: The pile structure causes multiple internal light reflections that trap light

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

  6. When specifying paint colors for a room that will be lit with LEDs rated at CRI 80 vs. CRI 95, the main practical concern for a color expert is:

    Answer: Low CRI sources may render certain hues inaccurately, making sample selection under those conditions misleading

    A CRI 80 source may render reds and magentas poorly, so colors selected under it may look different under the CRI 95 source the client may later purchase.

  7. Optical brightening agents (OBAs) in white paper or fabric absorb UV radiation and emit visible blue light. Their primary visual effect is to:

    Answer: Increase apparent whiteness and brightness under UV-containing light sources

    OBAs fluoresce blue-white under UV light, adding luminance to the surface and making whites appear brighter and cooler than they would otherwise.
