Split Complementary Color

Definition:
A split complementary color scheme is an overall palate of colors that starts with a single color and incorporates two of the nearest colors in shade. Those shades compliment, or look nice with each other. Sometimes people will take two colors that look nice together, but play with the shades to find the split complementary color scheme.

Explanation:
The green of the curtains was my starting point for seeing this as a split complementary scheme.
The pattern of the bed cover appears to be a tint of red-violet.
The red-orange of the pillow is the third color.
