Deep Black Chalkboard

In a dimly lit room, a deep black chalkboard and a pristine whiteboard are affixed side by side on a neutral beige wall, creating a striking contrast. The chalkboard holds faint remnants of erased mathematical notations, while the whiteboard stands immaculate. Below them, resting on a sleek oak desk, sits a single lavender folder, its soft color standing out against the fading twilight.
