The correct answers are:
- Color can be used to create mood in artworks.
- Warm colors, such as reds, yellows, and oranges, can create an energetic mood in artworks.
- Cool colors, such as blues, greens, and violets, can create an relaxed mood in artworks.
Because the colors create a mood in an artwork. They can't possibly neutralize it. There are different kinds of moods: energetic (for which use brighter colors), and relaxed (darker and cooler colors: blue, green, violet, grey).
