Thank you so much. I just found it myself and ordered a sample from Lee Jofa but it's nice to have it confirmed

Thank you so much but there are three colors and two look very similar, is it the 55 or the 56 colorway? Does anyone know? One looks pale green and one sort of pale blue gray on screen which is what I'm guessing this is. But I am only guessing! Very pretty, great job on the bathroom.

I think judging by the color of the leaves it's the colorway with the pale blue background. Hope that helps!

Judging by the color, this must be color 55.
