Hello again,
alec:
Sorry to hear about that. My only solution right now is that if you have any red/green dual color LEDs in anything that you swap them out for two new LED's that have the colors you do want, provided the drive voltage is enough to power it of course.
Most of the green and yellow LED's come in around 2 volts so you could swap out a yellow for green, maybe that would help.
Another idea is to use two different LED's of any color that can light in that application but separate them from a distance, like even 1/4 inch. One on the left, one on the right, or one up and one down, like they do with traffic lights. That way you can always tell which one is lit. Yes it takes a little work but assuming you dont have that many to swap out you're ok.
If you dont want to do that maybe you can try a very small prism, where it is mounted to the front of the LED. The different colors will project in different directions, maybe enough to help tell the difference.
The nice thing is that the red/green or any other multi color LED i've seen has more than one LED mounted at the same horizontal level, so they are spaced apart by some very small distance but some distance nonetheless. That means that for an LED that is permanantly mounted the orientation of the red might be on top, green on bottom, or vice versa, or left and right, or south west and north east, etc, diagonally. You might get someone to tell you which colors are which then note the position so you can always tell.

Yes, so many colors in the range for yellow makes it hard to get the right color.
Manufacturers dont seem to want to allow the selection of a given color. Very strange. Their process must not be that accurate.

I have read that some (or maybe all to some degree) insects are attracted to yellow light more than white light, or something like that, and it had to do with food or mating cant remember which now. That means it could help catch the critters or maybe keep them away.
Brighter light could make a difference too though. A 500 watt light will probably attract more than a 50 watt light for example.

Yeah i still havent looked for any data on spiders and light color. Might be interesting though to find out if they have any color sensitivity. If it say Red, we could go out an buy a whole bunch of red LED's and set them up around the house <chuckle>.
You know what....i bet they dont like any light, or at least prefer little light. Just a guess though because maybe they evolved to realize that insects like light so they should build their home near light too. I have no idea at this point though, just guessing.
