I like to paint and I’ve noticed many interesting parallels between painting and emotions.
For instance, to express a spontaneous quality, I’ll work quickly, applying thick strokes of vibrant colors in one application. This reminds me of the strong primary emotions of anger, fear, sadness, happiness, disgust and surprise, because they appear in a flash and demand urgent attention.
More often though, I’ll use layers of thin paint to create depth and luminosity.
In many ways, that’s similar to how we experience feelings.
