This year my marble queen gave me a tri-tone leaf!

My marble queen pothos decided to put out this gorgeous leaf some time this year. This is it fully mature! The new leaves from this vine are normal, so I guess I'll just have to enjoy this one happy accident!

Has anyone else had this happen? The leaves either have this greenish mid tone from variegation on the back, or a sort of bluish one like on njoys or p&j, only on the front. Do marbles come from those varieties? I'm so curious!
