1, i have two color-way s , they are equally both OK for me.

Alpha base color is GE1, the second choice yellow is CV , legend is CR, almost pure black.
2.

the second colorway is exchanging the base color with modifier color
Which one would you like better
3.
Some people may worry about dazzlingness of GE1 yellow as alpha base color and feel gaudy. Thus ,i show you some comparisons of three different yellows as alpha base color

4. i give some yellows' keycaps of GMK in real ones.

Among the three ,which one would you like best?
thank you for your negative and positive advice.
