Question

the white color shown here could be described as ______.

image of a white rectangle

○ a. red with 100% luminance
○ b. red with 0% saturation
○ c. red with 0% luminance
○ d. red with 100% saturation (option b is selected with a blue circle)

Explanation:

To determine the correct description of the white color in terms of red's color properties:

• Luminance relates to brightness; 100% luminance would be very bright, but white isn’t just "red with max brightness" (eliminates a, c).
• Saturation refers to color intensity (purity). 0% saturation means no color intensity (achromatic, like white/gray), while 100% saturation is vivid red (eliminates d).
• White (or gray) from a red - based color model (e.g., HSL) occurs at 0% saturation (all hue - based color is removed, leaving a neutral tone). Thus, "red with 0% saturation" matches.

Answer:

b. red with 0% saturation
