Create a lively and engaging full-page coloring scene that brings to life the madness of a Mahjong game being played amongst friends. Utilize medium greyscale tones to outline the intricate details of the simple line art. The central focus of the page should showcase a rectangular table, strewn with Mahjong tiles in various states of play. Each tile should be intricately designed with traditional symbols and characters, displaying the complexity of the game. Around the table, include four friends, each with unique facial expressions of excitement, concentration, and joy. The players' hands must be in motion, capturing the dynamic essence of selecting, shuffling, and placing the tiles. Background details should include subtle cues of an inviting room, such as hanging lanterns, cushioned chairs, tea sets, and Asian-inspired decor. Encourage the colorist to explore different shades by adding textures to the clothing, furniture, and tiles. The combination of the various elements must embody the enthusiasm and spirit of a friendly Mahjong match, while the greyscale medium ensures accessibility for colorists to add their own vibrant or subtle color schemes. Remember to maintain clean lines and a harmonious balance to invite colorists of all levels to engage with the art --ar 17:22 --s 50
