Why may it be necessary to test a mixture on the final surface?

Answer and explanation

Correct answer: Surface colour and absorbency can change the final appearance

The governing concept is the interaction between a colour medium and its support. Paper, cloth, wood, or a wall may differ in background colour, texture, and absorbency. An absorbent surface can make paint look lighter or less saturated, while a coloured ground can alter its apparent hue. Thus option D is correct. Brush size, the colour name, and palette drying do not explain why the same mixture looks different on the finished surface.
