What generally happens when black is added to orange?

Correct answer: A darker shade of orange will form

When black is added to orange pigment, the colour’s value or lightness generally decreases, producing a darker orange shade. A tint is the lighter version made by adding white, so option B describes the opposite operation. Orange does not become green merely because black is added, and it remains a secondary colour rather than becoming primary. Therefore, the darker shade of orange is the correct result in standard colour theory.
