I feel that the color scheme goes will on my Mammoth 75. Love the mild contrast with the grey on yellow keycaps with the black case. Overall a very versatile set that can be applied to a variety of keyboard colors.
The Alphas are a really nice tan and pair with custom almost black Mods with yellow legends. Such a unique set, things to note; the yellow is a pale less orange than a Space80 apollo Yellow and less saturated than GMK LUX and GMK Lunar.
