In which situation will the hue name of primary red remain the same while its value changes?

Correct answer: When white is added

The governing concept is the difference between hue and value. Hue identifies the colour family, while value identifies its lightness or darkness. Adding white to red creates a lighter red tint, so the hue name remains red while the value changes. Option A is correct. Yellow, blue, or green are different hue components; adding them shifts red toward another hue family rather than changing value alone.
