I was planning to change the LED lights on an XSPC Razor GPU waterblock from blue to green. I wanted to know if I could do this by covering the LED portion of the block with cellophane (or whatever else you call it

). Here are some pics for reference.

If the lights are originally blue and you put green over it, the result would probably be cyan.

Just covering the blue light with green will not make it green, it will be a mix. I say you try to experiment with different colors to try to get the color that you like the most

Blue LEDs only produce blue light. A green filter works by absorbing blue, yellow, orange and red light. You let through green light and everything else gets absorbed so will be dimmer.

This is what the light output from a typical blue LED looks like. The colors in the background are approximately what each wavelength looks like to your eye. As you can see, there really isn't any green there. You will shift the color a little, but reduce the intensity a lot.



If you want green, you will have to open it up, identify the LEDs that are being used, de-solder the blue LEDs and solder on greens.

I work in the LED industry and could help you with the LED identification and finding some replacements that are green. The nice thing is that the volume is low enough I could probably get you free samples.

You could also swap out for violet (UV) or white. Yellow, orange and red are more problematic because the LEDs are made of a different material and have a different drive voltage.
