Most colors that humans can see can be comprised using a CMYK color model (the standard color model used in offset printing) wherein all colors are a mixture of the process colors Cyan Magenta Yellow and Black. Mixing certian amounts of each of the process colors with certian amounts of other process colors provides the desired color, most computer printers work like this.

Using very intricately layed out but fundamentally simple arrangement of gelled lights similar to but of lower wattage than the kind of colored lights which provide a "wash of color" at musical concerts and some clubs and a room in which everything (walls, ceiling, floor, furnishing, furniture, etc ..) is of neutral color and opacity, full colors, hues, gradients and spectrums could then be projected on to all surfaces byway of a mixture of the amounts and degrees of illumination projected by onto the surfaces of everything in the room, assuming that the wattage was very low, the process of illumination would not be blinding and the overall luminance of the room could also easily be controlled providing actual atmosphere.

The actual control of the amounts of each process color could be arranged similar to that of a multi-channel mixing board in a recording studio but could look more like a seventies command center built into a bar or some other furnishing.

or would RGB work better?

       RGB *would* work better, which is why three-gun TV projectors use it. It's something about additive or subtractive mixing.
Neat idea.

       If the lighting is indirect, and the device has 3 dials to control individual hue intensities and an overall dimmer, it would be perfect and I'd get one. +   

       ...and welcome to HB.

       Angel, I'm sure you are right, It seems kind of nutty to attempt to "wash" anything with a black light anyways since an actual black light does not really exist .   

       XSarenkaX, the indirectness of the lighting is hopefully not an issue since the idea relies on many low-wattage lights spread out over the room, I of course don't know how feasible this is and I am two hundred dollars away from actually testing it.

       I don't get it. You want to light a room by shining little individual beams of light onto each object in the room? Where would these lights be? What happens when things get moved?
snarfyguy, Apr 19 2003
  

       Snarfguy : not individual beams shining on things, multiple low wattage color gelled bulbs emitting different amounts of luminance, brightness, and color.   

       fogfreak : that is one tri-color beam which would light one area with one color, that is not what I am proposing at all, perhaps I have not been clear in my half-bakeriness, I shall attempt to expand with verbose intent after more coffee.

       fdr, let me have at it, if I may. What I see this being is a total home lighting system using low wattage lights to bring colour to any or all areas of the home. To start off, the entire contents of the house are neutral in colour to represent the canvas. The lighting, which is the paint, can be adjusted so if you want cerulean carpet in the living room, you move some sliders and Viola! you have blue carpet. Now let's say you want the sofa to look chartreuse. Just set the sofa sliders to green and you are sitting pretty! That bust of Mozart on the piano? Set those controls to harvest and Wolfgang will scowl with a golden glow.   

       Does that do it justice? If so, I'm wondering just how many lights are in a "multiple"? (as in the sentence "multiple low-wattage color gelled bulbs"). I am concerned over needing bank after bank of bulbs, each object or area in each room requiring 3 bulbs to complete the effect. Remember, low-wattage normally means low-output.
Canuck, Apr 21 2003
  

       Canuck, that is a lot closer and having re-read my original posting after being graced with your annotation I offer this ammendment and further explaination :   

       I now realise that I should have made this clear instead of making no mention of it whatsoever; It is not my intention to have "the room" lit exclusively by these lights, the "multiple low-wattage color gelled bubls" in question would probably contribute to a very small percentage of the overall luminance of the room. I am not proposing a dark room relying on three thousand small colored bulbs to both light it up and flood it with color. I'm sure that inteligent conventional lighting schemes could provide the actual "lighting" of the room with little need for modification.   

       This is an important distinction in relaying my idea because turning off all the lights in a room and blasting a grey chair with a green bulbed flashlight provides a much different "feel" than lighting a grey chair with a green light in a room with other light sources.   

       There is a need to have a "clean" overhead light source in order to provide the intended results rather than a very dim multi-colored room.
fdr, Apr 21 2003
  

       Are there multiple light sources located just under the surface of each lighted object?
XSarenkaX, Apr 21 2003
  

       XSarenkaX : no

       Ok, a little physics before this one goes any further. The eye detects red, green and blue. The physics of it all is rather involved and complicated, but the end result is that unless you use red, green and blue lights whose spectra exactly match the response of the eye, you cannot actual reproduce certain colours - for example, you can't make a lot of the deep reds on a normal monitor.   

       To illuminate objects so as to change their colour, you'd need to compensate for the colour of the thing itself. If you shine red light on a blue sofa, it will look approximately black, although that depends on how red the red is. So everything would need to be white to start with.   

       And this idea of illuminating the 'rest' of the room with normal lights is nonsensical - the main room light would have no notion that you are trying to change the colour of the sofa, so now you would have the room light and your local area light competing and just making the thing a different colour again. It would be that much easier to not have a room light.   

       A small note on CMYK - you actually only need CMY; Cyan is green and blue added, Magenta is red and blue, etc. It only works for printed/pigment material because that absorbs the colours you don't see; a cyan object is absorbing red and reflecting blue and green, so it's no help when you're illuminating things. And of course the CMYK colour gamut is absolutely dire.
