    Default Purple arrows on V1

    Hello,

    New guy here. If you were to put blue LED's behind the red V1 arrows, will it light up purple? Have you tried this yet?
    I would be interested in this mod. As well as the other color combos offered out there.

    Thanks

    Single color LEDs emit over a fairly narrow spectral region. So I would think that the V1's red display cover would mostly just end up dimming the blue LEDs.

    I'd test it first by removing the display cover and placing a blue LED behind one of the arrows to see what you get. But in my experience, MEM-TEK is right, you can't really change the color of an LED by putting a colored lens over it.

    Why would blue light behind a red filter make purple light again?

    You have to think about it differently...With an LED you have colored light (color is based on temperature). With those crazy lights you see at the club, it's white light that passes through a sullofane filter.

    The OP is implying that if you pass a light that is blue in color through a filter of another color, the only light that you will SEE is that which was not filtered out. Deductive reasoning says that the light you will see will be that which survives blue and red filters...a darker color...purple.

    The flaw in this reasoning is that you're not passing the initial light through a blue filter...the light itself is blue as a result of temperature. Normally, the intensity of light is lost when you pass it through a filter (because you're removing some of the visible spectrum). With an LED, though, you're emitting the color you want from the start. There is no filter and therefore the initial intensity of the light is weaker.

    The reason I went through all that is to come to that last statement. There is no filter and therefore the initial intensity of the light is weaker.

    Since the emitted light is not as powerful, it does not do will with filters. The filter itself will over-power any initial coloring of the light. Essentially, you'll end up with a (darker) RED arrow because the filter is red and the "blue" in the light is not strong enough to counterbalance it.

    I'm not, by any means, a physicist...but if you don't follow my logic, trust me in this: after modding the concealed display, if you don't poke out the holes where the light comes through, they just look a darker shade of red.

    I was playing around with a blue LED, a 9 volt battery, and some gels for pro lighting stage lights, and the combination turned a deep violet. It looked very nice. But it was dim. One would need a pretty bright blue in that size that would fit the V1 board and socket to get it to work. The red hue did actually change to violet, but it didn't disperse the light as wide, and only the center of the LED was purple. The rest of the gel kinda didn't emit. But we're not talking a light of area that needs to be thrown on the arrows of the V1. I think it would work, personally.

    I think one would have to just try it and see on this one.

    You can get LEDs in just about every color of the rainbow nowadays... no reason you shouldn't be able to find violet LEDs to mod your concealed display with.

    Granted, it's probably the worst color for viewability, especially in daylight.
