I'm really liking the grey coloured timber flooring look particularly the limed grey oak by quick step:

During my research, all the grey coloured ones I come across are in an engineered oak. I know you can get some washed bamboo to get that really light coloured effect but I'm wondering if someone can enlighten me of a solid hardwood (not engineered) that will give the same effect/colour?
