How to solve the Blue Prince's Studio Blueprint Maze

The first set of clues to the Blue Prince Atelier and Holly Mount Blueprints maze comes from hidden hues, which are blank books, and their contents are revealed in the previous section. This book mentions:

• Original from Prism, three paths called.
• Three rays of light. Three kinds of shadow predictions.
• Three colors need to be calculated, eighteen.
• But one thing left and one hidden remains to be seen.

You can also check the surroundings in the main room of Atelier. You will notice that the estate has a rough draft, Auravei's old plan. You also tell you about the prism, the colors of the room, such as green, purple, yellow, red, blue and orange.
