This depends on what qualifies as “the lighting problem.” Generally, however, most dynamic colored lighting effects are considered entertainment rather than architectural expressions. Where colored light helps to render an already inherently colored architectural surface more richly or deeply and/or where select wavelengths of color dynamically change the perception of these colored surfaces, the solution of “dynamic colored light” may be appropriate. Where neutral architectural surfaces are transformed with colored light, static or dynamic colored light may be appropriate in defining the architectural setting. Overdoing these dynamic colored effects in permanent architectural lighting applications dilutes their impact and many times diminishes the character and quality of the very architecture they are to enhance (e.g., blue light on limestone).
