I've seen white keycaps with grey legends.
Well it looks like we are going have to "Make It So ! " ahahahah XD so if we can get say white ptb double shot silver legends key set made would people want to join in a group buy for that ?
AFAIK you can't get silver PBT material... Anyone feel free to correct me if I'm wrong.
Also, I don't think you'd get enough people interested in silver on white to meet MOQ.
the problem with "silver " and "plastic" is that you will need a very thick strip for it to look metallic.. otherwise a thin strip of silvery plastic will just look GREY
The only other way is to have a reflective silver surface, but that's not easily achievable on plastics, and it wouldn't be durable..
So you see, SILver plastic text is just not terribly viable for the font labels...
cutting out the stickers is your best bet.. for essentially "side printed" caps
