2 ticks for the HE "N" because, like Mark, I believe that the color effects the variant.
I believe that this is the "M" based on how they are using the variants in other Her Excellency models in this time. M for yellow, N for pink, O for white probably (I have seen white models but not an ad yet to verify the variant)
I think that makes sense, 'M' variant for me.
