Mixing Color in the air with LEDs.
 

Now I know you can get a almost every color LED (Light Emitting Diode). For this purpose lets say you can't. Lets say for this purpose only Red (R), Yellow (Y) and Blue (B) LEDs exist

If you mix the Light from 2 different LEDs with nothing but the air around the LEDs, will you get the proper color? Like if you mix (See Below) will you get the corresponding colors on top of the 3 colors you already have R, Y and B.

Y+B= Green (G)
R+B= Purple (P)
Y+R= Orange (O)
R+Y+B= ???? What would you get.

Then if not in the Air will it work down a 1 inch acrylic tube?

I need to know this for a project I am working on.

I would think if you move the LEDS quickly you can use the "persistence of vision" affect to your advantage. Have them spin.

You can try the tube. It sounds simple and cheap to play with.
You might also use a 555 timer and a counter or some other TTL chips to play around with. Be sure to current limit the LEDs. 15-20ma should be ok for testing.

Well, red yellow & blue are the primary colors in a subtractive color set, which means things like paint. Sometimes cyan magenta & yellow are used. In light, however, you need the additive primary colors, which are red green & blue.

Colors of the spectrum ... R|O|Y|G|B|I|V in exactly that order, can be obtained by manipulating the original three RGB colors. Thats all I got for you.

Now Why do you have to replace yellow with green?

Ask TV manufactures that question.


If you look at this picture, it looks like if you combine green and red, you will get yellow. ;)
