(0.15.x) Coloured lamps

[Factoruser]

• I'm missing the colour orange.

• The grey signal should produce a fainter white light.

• The black signal might produce a "ultra-violet" (dark violet) light.

• Coloured lamps should be brighter, though not as bright as normal white lamps, maybe except for the white signal.

• The colour signal order in the interface should be red, orange, yellow, green, cyan, blue, (violet), pink, white, grey, black.

Most monitors can't actually emit UV.

It should be obvious that the black signal should produce a "blacklight lamp" effect, i.e. emitting dark violet light. The visible spectrum part of UV lamps.

And I don't want every colours existing, but orange is a very basic colour that has been strangely forgotten.

I agree to have more color options, and a control of the Leds intensity , can shine more or less depending on their intensity as low, medium or high, I really like to do pixel arts in the Factorio, I miss the other colors and especially the black, mods solve this problem but in vanila would be a great addition.
