it's : violet, yellow-green, and yellow-orange. (just took the PF test and it was the correct answer)

Split Complementary. A split complementary scheme involves the use of three colors. Start with one color, find its complement and then use the two colors on either side of it. For example, the complement of blue-green is red-orange and the split complement of blue-green would be red and orange.
