Professional logo design. // SUBJECT Logo design for "Decembre 496", a month-long running challenge. The logo is a circular, modern emblem. // CORE ELEMENTS The central graphic is an abstract representation of progress: a stylized spiral or a series of 31 concentric lines that grow outwards, representing the daily increase in distance. At the very center of the spiral, the number "496" is placed, clean and prominent. As a subtle winter detail, the outermost circle is broken by six points, evoking a minimalist star or snowflake. The text "DECEMBRE 496" is integrated cleanly within the design, perhaps in a straight line bisecting the lower half of the circle. // STYLE & MOOD Minimalist design with an epic and motivational feel. The look is clean, technical, and elegant, like a high-end sports brand emblem. Flat 2D vector style. // COLOR PALETTE Monochromatic-inspired palette: Dark charcoal grey (#2C3E50) and white (#ECF0F1), with a striking accent of ice blue (#76D7C4). The logo must be impactful on both light and dark backgrounds. // COMPOSITION Balanced, circular design. The visual weight is centered, drawing the eye inwards towards the final number, "496". // NEGATIVE PROMPT --no detailed illustration, 3d, shadows, gradients, textures, watercolors, photos, serif fonts, complex shapes
