Talk of Bits etc indicates posters of an age where colors are computer screens and pixels only.
There are no such thing as indexed colors IRL...
Hate to be the one to tell ya, but that's one of those hard facts of life...
Read any book on theatre lighting and you'll find out that the first you learn is that with 3 spotlights in Red, Green and Blue aimed at the same white surface you're able to create any color. Only by using a dimmer for each spotlight. And as long as the dimmer(s) do not have any fixed levels the numbers of color that can be created is indefinite.
The concept of dimmed RGB LED
's is used in many applications. Jacuzzi use it as a sort of "color therapy" in some of their more expensive showers. LED
's are programmed to go through sequences of colors that are supposed to create various mindsets: Relaxation, energy, passion, focus e t c.
(Goethe wrote a lot about how colors affect people)
I am quite sure that the airlines will use the LED
- enhance their corporate graphic profiles (indoor "liveries" without paint...)
- create certain emotions: energy for "wake up calls", relaxation for nightflights e t c.
- Do cool things that will make people just enjoy the lightshow
But most of all I think the RGB thing is there because:
's are cheaper to run in the long run
- If you create white "base light" with RGB is gives you a bunch of cool options that white LED
's don't. At virtually no extra cost.
- And this tiny little feature turns out to be [one of the] most discussed things on this multi billion dollar development project.
Bet the engineers cry!
(And the marketing folks laugh)
