For a true indigo color, you should go Emerald. You can't filter blue. Filters block colors, and there's nothing but blue in a blue LED. Its one of the "pure" colors. Monochromatic colors are red, blue and green. Everything else is a mix. White is ALL colors. Your indigo color is blue with a little red in it.
Yeah, that's what I was afraid of.
If you want to filter for it, I would recommend getting Violet Amethyst, which is red and blue mixed, and then filter for the indigo. That would strain some of the red out of the existing mix, which would dim it a bit but probably not to badly. Filtering white for it would block way to much light and result in a very dim blade.
Yeah that makes sense. It could work without dimming it too much.
Emerald would let you mix it as needed and would be a bit brighter than filtering a VA LED, but the VA LED would be quite a bit cheaper than Emerald for a single color.
That's true. And if the blue filter didn't work out, I might be stuck with VA. It's a nice color, but not what I was looking for.
Thanks for the tips.
