Answer:
in what ways the artist used color
Explanation:
the first and last options are very subjective and individual therefore there's no clear way to properly analyze such a subjective thing. While the year the piece was created can give hints as to the inspiration behind it, there are more important factors when it comes to analyzing a piece. Colors often have emotions and moods that are associated with them, hence artists might purposefully pick colors to convey said thoughts and emotions.
