Why may hue contrast alone be insufficient when separating an orange object from a blue background?

Answer and explanation

Correct answer: Their values may be very similar

The governing concept is the difference between hue contrast and value contrast. Orange and blue can be complementary hues, yet a particular orange and blue may reflect similar lightness values. If their values are close, the boundary may disappear or look weak, especially at a distance or in reduced light. Therefore, the artist should also adjust lightness or darkness; the other statements are factually incorrect.
