Color is not perceived on its own, we perceive it with the color beside it. In the video, you can see the same color that will seem different depending on the colors that surround it. They can be seen brighter or more opaque, etc.
The most important thing is to make compositions where colors can create a kind of harmony, even though they are arbitrary or even though they are very contrasting.
