I want to love those Madewell jeans as well, but too destroyed for my taste. That whole collection is a really great spring palette, though.
Like greyscale, these colors do make me think of Nantucket reds/Breton chinos. Gives off a very beachy-chic nautical vibe.
J Crew also has their boyfriend chinos in a nice mauve-y blush. I would probably own these, but tried a different color last year and the fit is no good on me (they're too slim through the thighs).
