You might be right, but the first looks more like a golden mutation without patterning to me, the second a chocolate, and I think the third
is roux dilute but also italian-based (they're often mixed to make "autumn ambers"). #4 is definitely a snowie as you said! (Pearl-fee + silver).
I just think Egyptian is unnecessarily confusing for people getting introduced to other colors like 'pharoah' when the color had a perfectly fine name before. Plus, I think roux dilute rolls off the tongue in a sexier way.
Italian, pearl-fee , charcoal, pansy, and the last two I'd probably just call silvers since they seem to like to pop out all over the spectrum of tan-silver-blue
They are all lovely! Really really nice. You got some stunners in there and definitely some genetics that are not commonly floating around (esp the patternless golden/fawn/beige things and the chocolates. Tho everyone else seems to hatch chocos but me).
I'm a sucker for charcoals as you can tell and that tuxedo one is amazing

if it goes missing I swear it wasn't me
