Herman Munster was violet for better filming in B/W, but turned green for the first movie. I’m linking to the Google search because I’m not 100% sure this trope is completely true.
Raging Bull makeup supervisor Michael Westmore talks about how B/W makeup differs from color.
The The Munsters Munsters makeup looked awful in color.
On a related note, why Boris Karloff’s Frankenstein’s monster was green:
As for Pierce’s decision to slather Boris Karloff with green makeup: That was both a creative choice and a technical consideration. The color sensitivity of the film stock used in the 1930s meant that certain shades of green would show up on screen as a ghostly white. Karloff’s green makeup, then, both tinted the actor’s skin to a cadaverous pallor and gave him a decidedly different complexion than the rest of the cast. Soon the green tint began to show up in promotional materials such as this poster, and thanks to the popularity of the film and its sequels—along with Universal’s allegedly aggressive copyrighting of Pierce’s design—Frankenstein’s Monster has been green ever since.
