I want to know the answer to the following question:
What colors were utilized for interiors?
All the background I'm provided with is that "Techniques employed in the style included flatter, lighter motifs, sculpted in low frieze-like relief or painted in monotones en camaïeu ("like cameos"), isolated medallions or vases or busts or bucrania or other motifs, suspended on swags of laurel or ribbon, with slender arabesques against backgrounds, perhaps, of "Pompeiian red" or pale tints, or stone colours.". Is that enough to answer the question?
Answer: yes
