These mystery coloring books put a nice twist on a type of color-by-number book. I enjoyed the added challenge of riddles and a more advanced coloring style—and a couple of friends are already eager to try coloring in my books soon. If you love a mix of mystery and creativity, you might find these just as fun as I did. I wasn’t asked to share this, just wanted to talk about these unique books in case you love puzzle adult books. You can check out my review on YouTube, linked in my bio. #MysteryColoring #ColorByNumber #ColorByNumberBooks #MysteryArt #HiddenImage #PuzzleColoring #SolveRiddles #adultcoloring #adultcolouring #youtubecoloring #coloringpages #youtubecoloring #youtubecolouring #coloringbooks #colouringpages #colouringbooks
