This marvelous, Gothic-style hotel is both intimidating and inviting. Its tall, dark walls are lit up by tall windows that seem to beckon curious visitors in. In the center of the Hotel Transylvania, there is a large, imposing entrance emblazoned with gargoyles and adorned with a large sign. To create an inviting yet mysterious atmosphere, play with light and dark tones. For the walls, mix warm shades of grey, burgundy and brown in swirls near the windows and blend them with a darker shade of black near the entrance. For a more modern feel, color the window frames with a bright teal hue, while still accentuating the darker tones in the walls. Finally, decorate the entrance with vibrant, contrasting colors like bright pink, light purple, and vibrant emerald green.
