Polyptych is the technical name for a multi-panel picture, while diptych is the technical name for such a picture consisting of just two parts. Great example here from Kamigawa block, where the lands form a single panoramic image is a kick-arse polyptych.
White puts value in the group, the community, and its civilization as a whole. White’s ultimate goal is peace, harmony, and perfection — a world where everyone gets along and no one seeks to disturb the safety and unity that White had worked so long to forge. To govern and protect its community, White makes use of and puts value in a number of broad concepts; morality (ethics, religion), order (law, discipline), uniformity (conformity), and structure (government, planning).
Blue’s philosophy, like that of each color, is determined by its world view. To Blue, the world is opportunity. Within it, hide wonders and possibilities most fantastic: the stuff of dreams. Blue is characterized by the desire to know the world’s secrets and to make those possibilities real. The belief that dream can be reality - to which Blue holds fast - is belief in tabula rasa, the blank slate.
Black looks on the world and sees just a plain reality: Power controls. Power says who rules, and who dies. And whether the weak can see it or not, they are no more than slaves for the powerful. The essence of Black is to see one’s own ego as so supremely invaluable, that this prospect of enslavement, of subordinating that ego to another, is utterly inadmissible. So, to be in accord with its perceptions and beliefs, Black simply must discard all obligations but to acquire power for itself. It can be no less than the one supreme being who is subordinate to no other, the possessor of all power in the universe - it must become omnipotent.
Red looks on the world and sees adventure. Life is a chance to experience something - many things - and for Red, there is no more worthwhile endeavor than to enjoy life by the adventure it offers. Experiences are what life is about, and to appreciate the full range of life’s experiences, Red lives by emotion. What makes one laugh, what makes one cry, what one hates and what one loves, these make up what a person is. A person can look only to these, believes Red, to find one’s wishes and desires in life. Deny these, and life is meaningless.
Green is the color most in tune with nature. Whereas the other colors seek to modify the world around them, green believes that the best course of action is to simply allow nature to take its course. Thus, green is often seen as the least confrontational of the colors: it does not seek to impose its values on others; it just wants to coexist as peacefully as possible. This does not mean that green will not defend itself when it feels threatened, but it generally will not seek to impose its opinion on others.
