Design one mobile app icon for a planner app, shown alone and centered on the Presentation Background with a soft, understated shadow. Use a standard rounded-square silhouette with a full-bleed Secondary Color background and a simple calendar-page symbol in the Primary Color. Place the Central Symbol as one bold, highly legible mark on the calendar page, filling roughly 60 to 70 percent of the icon's visual area. Keep the calendar geometry flat, spare and instantly readable at 48 pixels, with confident shapes, even padding and no fine details. Use only the Primary Color, Secondary Color and white where needed, with no gradients, gloss, border, extra text, labels, logos or watermark. Show a clean front-facing view with balanced spacing and crisp edges.
Use these details:
Central Symbol: "7"
Primary Color: "red"
Secondary Color: "white"
Presentation Background: "plain light gray"
Using your own logo, product or face? Attach it in the chat and say which of the details it replaces.
Your result will come out close to the example rather than identical to it. Change the details to make it yours.
