I agree with Ivy here tweaking the setting for glow from 2 to 1 made illumish shades so much more acceptable to me.
I found that setting by accident because I really hated Illume and Glitter in a lesser degree.
While shades are a matter of taste and there are certainly furs I prefer without a shade and at that point it is up to me to decide if I make a 9T just for the sake of making a 9T or do I skip the shade.
Same goes in my case with the eyes I love a big pupil with a mysterious eyes shape overall way better than the "perfect" eye.
I devided my cattery in cats I make for me and to have as pets and those I breed for the market as breeding tool for other breeders.
It is funny you mention it Ivy porcelain was right away my favorite shade for the same reason as you
