What effect is created by using a thick line on the main figure and thin lines in the background?

Correct answer: Main figure will stand out more

Direct answer: A is correct. Line weight means the apparent thickness or visual strength of a line. A thick or heavy line attracts more attention, while a thin line usually creates less visual emphasis. When the main figure is drawn with a heavier line and the background with lighter lines, the viewer’s eye is guided first toward the main figure. This creates emphasis and helps establish a clear visual hierarchy: the important subject appears stronger and the background remains secondary. A is correct because contrast in line weight makes the main figure stand out. B is wrong because a heavier outline normally increases visibility rather than making the figure disappear. C is wrong because line thickness does not by itself change whether a colour is warm or cool. D is wrong because a drawn line can suggest texture, but changing its weight does not make a two-dimensional surface physically touchable. Memory cue: heavy line attracts, light line recedes.
