No one "side" of a human being is their one "real side". A usually cruel, nonchalant, inexpressive, dispassionate person being expressive, showing kindness and compassion does not mean they just revealed their "true colors" and "real self" (unless they really were demonstrating an act for some reason, somehow). A usually composed, kind, polite, reasonable person showing anger, cruelty, high selfishness, and/or betrayal is not revealing their "true colors" or "true identity" and their "real side" unless, again, they were entirely pretending all along, hiding motives, etc. (Even then, I don't find that kind of wording to be helpful or accurate, I don't like it). Importantly, if a person is simply standing up for themselves, they are not showing their "true (bad) colors". Just because a person is showing a side 'opposite' to them or behaviours, qualities, traits different or distinct from what they usually display, does not mean they are showing who they actually are and their real self or colors, and whatever they demonstrated or did previously are all just "fake" and false and not even them. All of it is them, their kindness and their cruelty and their concern and their indifference; human beings are not static and they are not "one if not the other" or "the other if not one". They are highly complex and enormous within. I think..we are infinite within, as ourselves. That might get misinterpreted. All the supposed negative and positive qualities of a person are part of them, if they display traits that strongly differ from their usual, real self (as in not a kind of pretension [but even then they are still them, not a different person of course]) they are not revealing "who they actually are". They always are themselves. You always remain the person you are. A person engaging in a social interaction and the same person painting are not two different people, they don't turn into a different person, no, not even metaphorically (that doesn't make sense); anything and everything they do and say, the choices they make, what they express and reveal, all reflect them as an individual and are all expressions and manifestations and extensions of them.
You are not one thing when you are writing and someone else when you are eating at a dining table with others. Everything that you demonstrate and do are all you, from inside you, even if you seem/are/act wildly different in those two scenarios or experiences. Even when you are pretending and faking, trying to be something else that you are not, or which you are not naturally, trying to be someone else, and even when you don't know 'who' you are or are unsure of/about yourself, you are still (being) you. You just are, as yourself, and you don't have "one true side" and just because you are being 'different' from how you usually are does not mean you are showing your real self. Because you have various contrasting qualities and abilities that does not mean you are "fake" or "inconsistent", "hypocritical", "contradictory" or that some qualities/states are your "true colors" and everything else has no meaning and no reality (or authenticity) to it and aren't truly you. A person who shows unexpected and unusual kindness is not "actually kind", and a person who grows angry, tired, and intolerant and shows their rage or gets harsh is not "actually rude". What about their 'usual self' with the traits they display, then? That is not "actually" them? If they are really compassionate, then perhaps that normally brutal, unkind person is just someone else who looks exactly like them? 'They' are actually also or actually can be kind or mean or generous, etc., they are not one single thing or a bunch of things all similar to each other or strung together. Or merely the qualities/traits resulting from either the unconscious or the conscious. You are "actually" complicated, with depth, and have been shaped and affected all throughout life in countless incomprehensible ways and you have various traits, abilities, emotions, and feelings, and "sides".
You never stop being and reflecting yourself. No matter what situation you are in, who you are talking to, what you are immersed in, what you are doing, what you are thinking, what you are experiencing, who is speaking to you, what happens to you, what you feel, how much you change, grow, develop, mature, learn, you always are the person you are. Within yourself and as yourself you change, grow, and evolve but you always are you and 'you' are not a being of complete staticity but something of high complexity and enormousness and diversity with an immanent, intrinsic, significant core.
