I have never been drawn to white keycaps but considering the price + the overall quality I' would be so in for a set of each!!!!
Me thinks if the sets are all white, then maeby we should have the legends in same color as the 5 sets we received, that way we can mix and match the colored sets with the new white sets with the matching color legends and have retro style look to it.
Not crazy about white but I'll be in for 1 of each if the legend colors match out current color GB keycaps ( black,red,green,yellow,blue)
