Any ideas of how to change the colour of diffused LEDs, can they be painted or dyed in any way?
I'm currently doing a project involving LEDs and want to be able to get the colour of them to match into my colour pallette, which is quite metallic and pastel, so I was wondering if there is any way of taking white LEDs and then changing the colour. Would something like glass paint be ok, or any kinds of dye that people could suggest? Any hints, tips or suggestions would be greatly appreciated. Thanks :)

As educator Kiteman points out a white LED is a blue LED with red and
green phosphors. You can use a translucent plastic light filter to block the
colors you do not want and pass those colors you do.
Metallic and pastel is a tough combination, perhaps a near filter with
glass paint to promote the metallic liquid sheen.
As for the pastel there may be a transmissive chalk that can help render
that on your filter.

+1 Also, test any paint you use on a spare bulb (not one in your project) to test the finish, not only for the color result, but for the coverage. Paints can leave a "streaky" coverage as they are difficult to get perfectly even.

Why not use RGB Leds to get the right colour ?

Yes, glass paints will filter the colour of a white LED, but the results may not be exactly as you plan, since white LEDs are actually a mix of red, green and blue light.
