A close up of a hourglass on a desert with a sky background

An hourglass with two halves of contrasting colors. The upper half, filled with sand, represents the days that have already passed. The lower, empty half represents the days that are yet to come. Minimalist style, with simple lines and geometric shapes. Upper half A warm and vibrant color, to represent the energy and life of the days that have passed. Bottom half: A cold and calm color, to represent the tranquility and uncertainty of the days yet to come. A soft, natural light that illuminates the hourglass softly and uniformly. A neutral and diffuse background, so that the attention focuses on the hourglass.
