The Kerbal skin color name is BADASS, no joke.

Since hex color dosen't allow 's', it says "bada55", but it's the Kerbal skin color! www.color-hex.com/color/bada55

Pretty sure there was a thread about this before. This is nothing new.

It's been a more-or-less known piece of trivia for quite some time, actually.

Incorrect. As mentioned above, this is old news, and as detailed on the KSP wiki, the color is similar, but not exactly equal, to #BADA55.

The closer speculation is that it's #B4D455, which is still colloquially "badass" and even closer to their average hue.

But we're splitting hairs, the fact that their average hue is close to #BADA55 and #B4D455 is too incidental to be a coincidence given their hidden "BadS" traits, too.
