Comment 4 for bug 2008918

That seems like a reasonable approach to me, Galen. One less thing to have to remember when implementing a modal! I added a second commit removing bg-info to this branch: user/sandbergja/lp2008918-modal-header-color-2

FWIW, I have exactly no ties to #062C65 -- it was just a random color with good contrast that I saw in a recent commit.
