It is, but it doesn't suit me. Intellectually I can see shades of gray and appreciate them, but emotionally I'm not gray at all. Being as I see myself emotionally driven rather than logically... It's uncomfortable. [Self portraits, while I don't really like my features, I do favor my coloring as saying something about me.]
It's like being in a skin that doesn't fit right, or looking in the mirror and thinking that the person you're looking at- while logically it is you with the same features and coloring- is intuitively not the same person at all. It's like you feel like you're not yourself, and for an introspective person it's like you're not in touch, intimate, with who you are anymore.
Given personal circumstances, all it does is inspire anguish.
I understand what you mean, for I have sometimes felt the same way. In this case, I reckon the only thing you can do is to "unleash" the colours inside you. Find a way to let those emotions come out. Let your feelings lighten your face.
