Like many fans of classic videogames, I have had to deal with the yellowing of older consoles. There are various causes why this happens, largely a combination of ultraviolet radiation from the sun and fire-resistant material sprayed onto the machines during production (to keep your system from bursting into flames). A number of solutions have been offered over the years, most are very similar to dying your hair, and they can be rather time-consuming and challenging.
However, there is an easier solution: direct sunlight. I read one person's account of leaving their browned-out vintage console in the sun for several days, which restored the original color. My Sega Saturn was beginning to turn brown on the front side, so I thought I would put this hypothesis to the test and try it out.
I put my Saturn onto the living room windowsill where it receives lots of direct sunlight throughout the day, and just left it there for a week. I didn't take any "before" pictures and the condition wasn't terrible, but it was very noticeable and I wished to see the original light grey restored.
As you can see, the experiment was a success. I took these photos last night and everything looks great. The color is uniform across all sides and there doesn't appear to be any side effects. Fortunately, the Sega and Sega Saturn logos weren't affected, as they weren't exposed to sunlight for very long.
If you have any older computer equipment that suffers from the yellow/brown condition, I would recommend the "direct sunlight" method and see if that helps. Just place in direct sunlight and leave it there for several days or a week, and try this method before moving on to the hydrogen peroxide.
