It seems that at the very least, kagune do come in different colours. The most common colour seems to be red which makes sense, but even the manga shows that there are some different colours, like Yoshimura and Eto's pure white kakuja's as well as Arata's pure black kakuja.

They might not be as vibrant as some of the ones shown in the anime, but it's still possible I guess.
