Yeah, they covered my concern above. The combination of the low contrast and small point size will make it really hard to read, especially if the inlay has texture to it (not sure if B mold does).
My other point is not overdoing the inlay. It’s a very small space, so I recommend you be deliberate and purposeful with what you add.
I also recommend looking at other inlays and reflecting on what you like and don’t like about them, to help inform your views.
An inlay, however, is art. Ultimately what looks good to you is what counts. I’m throwing out ideas to help test your views and make sure you’re loving the final design.
