ERIKA IS PAINTING A FOREST. SHE WANTS THE TREES IN THE BACK TO BE DARKER. WHAT SHOULD SHE DO WITH HER GREEN PAINT?
1. ADD SOME BLUE TO CHANGE THE HUE.
2. ADD A LITTLE BLACK TO CHANGE THE VALUE.
3. ADD SOME WHITE SINCE IT IS TECHNICALLY NOT A COLOR.
4. ADD ANOTHER LAYER OF GREEN TO DEEPEN THE INTENSITY.
