In a cinema the projection screen is white (or light gray), but the area around that, and the other walls, are typically black or some very dark color.
For the Pyra case, I don't want any bright color (including shades of white) for the same reason.
We shouldn't discuss colors in terms of RGB, by the way. There are too many colors that cannot be reproduced using just RGB. Also, our monitors are probably not calibrated well enough, and single color data points do not suffice to convey the perceptual properties of surface materials.
