Are you going to document your process?
well it'll be at least a month before I try it, but I have used RITT before quite a bit (to dye clothes) so I'm somewhat familiar with the dying process itself. Based on that (and from what I gathered on the site that XS linked to):
--warm or hot water (in my experience, you dont have to boil it on the stovetop, so long as the water is very hot it will work, though with clothes they say the color sticks better if its boiling, but in the case of plastic keys, I dont think it would be wise to boil the plastic, as it may melt, who knows). Bucket (or if on stove, large spagetti saucepan).
--pour in the RITT (use whole package; if you want pink instead of red, buy the pink RITT (rather than trying to use half a packet of the red RITT). RITT comes in every color you can imagine. Also comes in powder versus liquid, either will do.
--Mix it well, put in the keys (or, clothes), and keep mixing, dont stop mixing. The reason you want to keep mixing is because otherwise you will get uneven dying. This is true for clothes and according to some of the comments on that site, is also true of keys). Keep mixing for 10 minutes.
thats it, take them out and let them dry before rinsing. That should more or less work (it will work for me cuz I'm actually only interested in "tinting" the plastic frame and/or keys, not in covering them up completely). If the color isnt dark enough, I think hotter water may be required (and maybe in that case it may make sense to bring water to a boil on the stovetop and then turn off the flame, rather than just using hot tap water).
Also in my experience, some dye colors work much better than others. The colors that work very well are black , navy blue, green, and red. The other colors tend to "deeply tint" rather than color. (Even with the above, sometimes it will take two dye-cycles to get the right shade you want, for instance, if water isnt hot enough, black will produce charcoal gray (which actually personally i'd prefer), and red will produce dark pink, etc). So you may want to apply it multiple times.
On the whole this does sound like a relatively very easy way to add a splash of color to the keyboard without having to mess with messy paints and sanding and all that. RITT costs like $1, is available everywhere, and in a rainbow of colors, and all you'd have to do is pop off keys and frame, dye it, pop them back on 10 minutes later.
When I do do it, I'll definitely document the result with pictures
P.S, and dont forget to buy red RITT just for the escape key
