The color wheel is organized into a circular spectrum of hues that shows the relationship of each hue to another. Color harmonies demonstrate the patterns in these hues.
Not everything in the room has to be a share of green. To get the monochromatic effect, a bold green is used on large items that are close in proximity.
Again, not everything in the interior has to be teal or lime. The furniture against the lime wall demonstrates a chic analogous color scheme without looking tacky.
Notice how not everything in the room has to be one of the two colors in the scheme. Throwing in other neutral colors helps the room look put together and not overwhelming.
We know this color combination works in an interior because it is a color theory. The colors do not fight with each other and make the room more interesting.
