Blue is one of my favorite colors. Good thing, as my BAT VK-D5, Stealth XXX, PS Audio phono stage and Synergistic MPCs, all have BRIGHT, blue LEDs. Love 'em, along with the glow of my system's tubes, in the dark. Anyway; here's a possible solution, for you that hate them. Having some leftover .002", red celluloid, from gapping voice coils while in the reconing business; I tried a piece over my LEDs. It resulted in a very pleasant fuchsia/magenta, at a reduced light level. If you like green; yellow should render some shade or another. Just find the thinnest, transparent acetate/gel sheets you can and change your LED's color. Attachment: up to your creativity/prerogative. ie: (
