Final answer:
The Peale family of painters used different values of colors to make objects in their paintings look realistic.
Step-by-step explanation:
The Peale family of painters used different values of colors to make objects in their paintings look realistic. They understood the concept of shading and highlighting, using lighter and darker tones to depict form and depth. By using this technique, they were able to create a sense of realism and three-dimensionality in their artwork. For example, in Charles Willson Peale's painting 'The Staircase Group,' the play of light and shadow on the figures and objects gives them a lifelike quality.
