I suppose the most marked example of color as structure is in the Byzantine use of mosaic decoration that becomes architecture. The decoration of the interiors so related to the form that they fuse. In less elaborate interior design this is always the ideal approach to color - used not only as just color alone.

Interiors speak! Rooms emphasize whether one exists or lives, and there is a great difference between the two!

Too many bright colors make for congestion. Too many bright colors need, above all, contrast in value, to eliminate vibration.

The overscaled compositions being produced by so many abstract painters, which are full of movement and use of color, are ideal example, ideal transformations of an entire wall and entire room.... There is no denying that one of the major attractions of these successful large compositions is their structural decorative use in the contemporary scene... That these large canvases can be superbly decorative may not be considered complimentary by some of the artists involved.

The combination of an individual[i.e., a client] with a positive idea of living and a good designer is the great force in contemporary decoration. I don't care how good the designer is, I am sure that he [or she] would rahter have a person with definite ideas rahter than have to work with a negative figure as a client.

Control, edit and distill.

It is obvious that any rather non-color, monochromatic design is safe, easier, more generally restful and with life being the hurdy-gurdy that it is, more and more of us prefer and interior giving the maximum response.
