Inkheart was one of my most formative reads as a child, and the whole series was very important to me (though the romance in book three pissed me off as a Meggie/Farid shipper and diehard hater of endgame love interests and major villains being introduced in the last installment of a series). I was thrilled when I saw that there was a new book set in the same world.

Ultimately, The Color of Revenge was fine. It's a one-off book with a plot mostly centered around Dustfinger, though Dustfinger does very little and has no real character development. The real character development belongs to the Black Prince (I'm not gonna spoil anything cause I legitimately recommend reading this book just for his story) and somewhat to Orpheus, who is the primary antagonist. There are some evil women and there's also a fun lesbian (yay!), but this book is overall pretty focused on the adult man characters. 

Overall, glad to have spent time in this world again, and it's definitely better than other unasked-for continuations of middle grade faves I've read recently (looking at you, Rick Riordan), but overall not something I think you need to read and definitely not Cornelia Funke's best.
