I know styles change and even Roland and Yamaha try to make their arrangers look cutting edge, BUT I would prefer keyboard styling that was more professional looking than showy. Blue is OK, so is silver or black, even that deep cherry Korg had on the Karma, but to mix colors begs for a sense of fashion, which I don't think should be part of the arranger. FWIW.

Angular lines as opposed to bubbles and big rounded edges.
