The smaller the piece, and the fewer the color cells, the more important the color relationships become. Such a compact and concentrated statement is an excellent opportunity to construct the visual equivalent of a musical harmony, or "chord."
I was seeking a cool overall psychological color temperature here as well, keeping to an analogous (closely related) color range between green and deep blue.
But the process is about pattern as well as color, so hopefully the variety of expansive patterns allows the eye to linger in fascination within an otherwise calm oasis of harmony.
