I got the BL3 and at first I thought it was too white but I’m use to it now next time I’ll get bl4 or B1

What tones does the BL4 have? Does it have the same yellow hues as the B1? Because in some photos it looks grey/blue toned

I’m trying to figure out how to get composite fillings in a lighter shade than b1. I have crowns that are the shade bl4 and I would love for my fillings to match. Any recommendations?

Bleach4 is like 1m1 ?

Should be a bit lighter since it's a bleached shade.
