Science fiction Book Cover Design (Evoking simple, calm, and professional)

Visuals: A soothing turquoise sky dominates the background, creating an ethereal sci-fi aesthetic. In the top right corner of the turquoise sky lies a single small golden gear symbol, subtle yet marking the theme of personnel performance evaluation. At the bottom of the cover, a minimalist purple and golden bar chart spans horizontally, providing a scientific and structured feel. The main title is center-aligned, written in a semi-bold classic font, radiating professionalism. The author’s name sits neatly and modestly beneath the title in a smaller font.

Typography: Typeface for the title is “B Lotus”, a clean, semi-formal Persian font for readability. For the author’s name, "Iran Sans" with a lighter weight is used, which contrasts gently with the boldness of the title for an elegant look. Book title font size is larger, making it the centerpiece of attraction.

Layout: 1. The turquoise sky spans the entire background. 2. Golden gear is positioned in the top right corner, balanced and unobtrusive. 3. The book title is centered, taking up prominent space, while the author’s name follows beneath in a smaller font. 4. The purple and gold bar chart adds graphical interest at the bottom but does not overpower the text elements.

Explanation: The visual composition of this design reflects the theme of 'evaluation' with the golden gear and bar chart as symbols of analysis and systemization, while the turquoise sky adds the essence of sci-fi, evoking curiosity and intrigue. The typography choice of "B Lotus" and "Iran Sans" ensures readability in Persian while keeping a balance between formal and modern visual appeal. The layout is methodical, positioning the golden gear and bar chart in a way that adds structure but doesn’t distract from the core elements, such as the title and author name. The cover material and finishing with Spot UV give the book a premium aura, making it stand out while also feeling pleasant to touch, which is key in attracting readers to a sci-fi professional-themed book.
