Technology Blue White Silver-Gray Innovation Beauty Purity Freshness Modernity Clearness Book Cover Ideas with Cityscape Mountains Halo Engineering Pipelines Water Droplet Water Pumping Station

A deep blue background dominates the cover, symbolizing water and freshness. In the center of the design, a large, glossy blue water droplet encapsulates a luminous, modern cityscape, prominently featuring Milad Tower and Azadi Square from Tehran. The clear city details are surrounded by soft gradients of blue and white to enhance the idea of purity and innovation. Below the droplet, two to three thick silver-gray pipelines, gleaming with metallic sheen, stretch outward, connecting the city to the foreground with a futuristic water pumping station subtly resting near the base. The pipelines feature intricate embossing, evoking an engineering perspective. In the far background, fading into the horizon, snow-capped mountains add depth. A subtle halo of light resonates around the drop, enhancing the freshness and modernity feel.

For the main title, a bold sans-serif typeface (like "Proxima Nova") in white with light blue highlights to seamless blend with the design theme. The author’s name, "شهری مدرن و پیشرفته...," appears in Farsi in a slightly smaller and elegant "Persian Sans" style font below the title, centered, contributing a sophisticated balance.

The title is positioned at the top-center in large, bold letters, ensuring visibility. The blue water droplet containing the cityscape is the visual focal point in the middle of the cover. The pipelines are arranged below, extending horizontally and creating a foundation layer. The author name rests calmly below the main image, while the mountains fade into the upper horizon behind the droplet. The pipeline embossment leads the eyes from the bottom toward the main elements.
