This whole talk to type thing doesn’t work well for me.
I have a Firing Pin VPI Axanthic (fire pinstripe vpi ax) that should stay pretty grey into adulthood.
So fire and axanthic together is nice to keep grey tones and pastel on occasion but axanthic tends to brown out a bit with most combos. There’s not really a grey single gene you can introduce to Enchi to make and Enchi grey besides axanthic and they won’t stay silver most likely without a shot of pastel or fire.
