Keycap bleach/fading test

Results of an experiment investigating the effect of sunlight on an anodized keycap's color – committed by flehrad.

Anodized metals in the full sun will definitely fade, but how much will they fade through a window and flyscreen?

Even though this experiment seems to be a follow-up to last week's anodized aluminum discoloration post – Don even refers to that post in the video –, he set up this trial three months ago! He must be a freakin' oracle.

So a bit of an experiment that took 3 months led to this video. How much sun fade happens in full spring morning sunlight? I put my Mountain Keyboards keycap to the test by sitting it against my balcony window for 3 months – flehrad.

To say the truth, I can't really see any difference at this point that I couldn't explain with the lighting and reflections, but the experiment continues!
