Final answer:
Warm colors indeed create a cheerful and inviting mood in a room, as evidenced by their comfort-evoking associations and their use in art, such as in Renoir's 'Mother and Child'.
Step-by-step explanation:
The statement, Warm colors create a cheerful and inviting mood in a room, is indeed true. Warm colors, which range from yellow to red on the color wheel, are known to evoke feelings of warmth, comfort, and hospitality. This is because warm colors are associated with things like the sun and fire, which are naturally comforting to humans.
In art, these colors can create a mood that is cheerful and inviting, as illustrated by Pierre Auguste Renoir in his painting Mother and Child from 1886. This painting largely utilizes oranges, pinks, and yellows, effectively creating a warm, cheerful, and inviting atmosphere.
