I have a theory about the name Blue Jean I think it's named that because jeans go with everything not because it's the color of blue jean, know what I mean? Ironically it does seem hard to pair with more recent dark washes in denim but it is a very neutral blue and a classic. It's more of an iconic H color to me, very distinctive. There are so many H blues but all the mid tones seem hard to wear with denim. It's not a color for me, I am more of a black, navy, gold, gray, olive and white fan.
