Hue is the most obvious characteristics of color. By changing the color of the outer box to a more similar inner color, it lessened the hue, whereas the opposite color brought out a greener green.
Saturation is the purity of color. The bright orange brought out a rich and full color with it being opposite it from the color scale. While the “indigo” color which was closer to the blue, made the colot more dull, bringing the saturation down.
Value is the lightness or darkness of a color. By having a brighter and more vivid background color, the first box brought a lighter pink color. By having a darker, more similar background color for the second box, it made the inner box darker.
