Vortex Race 3 DSA keycap color

Does anybody know which SP PBT color code is a good match for the stock light grey alphas on the Race3 ?

Are they a match for SP DSA Granite (which has GKK alphas)?

I’m thinking aboout ordering a few DSA blanks from SP and trying to somehow ghetto dye-sub my language’s special characters onto them to complete my layout. I only need to do the 5 keys to the left of the ISO enter, the rest of ISO-DE that my board came with is a pretty good match for my native ISO-HR.
