Recently, it was told that in the next Dragon Ball Super movie, Piccolo was going to be featured with the original color of his skin in the manga, which had yellow spots instead of the pink ones he had in the anime series.
Now how about the blood? Piccolo it is apparently shown with blood in 3 different colors in the anime, red, purple and green.
Which was the original color of Piccolo's blood in the manga? Is there any source material or colored manga page which shows this?
