Why can an artist view a coloured picture in grey to check its value structure?

Correct answer: Because the relationship between light and dark values becomes clear

Correct answer: A. In a grey-scale view, hues and most colour differences no longer distract the eye; the artist mainly sees the relative lightness and darkness of areas. These light and dark relationships are called values. By checking them, the artist can decide whether the main subject stands out, whether the focal point is clear, and whether the picture suggests convincing depth. Option B is wrong because saturation is not increased; colour saturation is removed or greatly reduced. Option C is wrong because changing the view to grey does not create a new perspective or alter the arrangement of objects. Option D is wrong because texture may still be visible through its light-dark marks. Memory cue: value means “how light or dark,” not “which colour.”
