The majority of computers are now using LCD screens, which make it difficult to see the keyboard if you have a dark background. White keyboards also tend to be much brighter and easier to read at night when compared with darker colors. A number of people who purchase white keyboards do so because they want their keyboard to look clean all the time- not just during use!
I’ve always been a gamer, but I never thought about the color of my keyboard until recently. White keyboards are often marketed as ‘gaming’ keyboards and many people who play games will exclusively use white keyboards because they think it helps them do better in their game.
Unfortunately, there is no scientific evidence to support this theory and we can’t know for sure if it’s true or not. On the other hand, white gaming keyboards may make your desk look cleaner and more organized! So why not go with what you like best?
