Rainbow Concentric Circles - Bold Color Spectrum Design #283537 (License: Personal Use)

This high-contrast digital illustration features six perfectly centered rings in classic rainbow order: red, yellow, green, cyan, blue, and magenta at the core. The bold, flat-color design emphasizes chromatic harmony and visual impact against a pure black backdrop, making it ideal for educational, artistic, or branding contexts.

Used in graphic design resources, color theory tutorials, UI/UX asset libraries, or as a decorative element for websites focused on creativity, psychology, or inclusivity (e.g., LGBTQ+ pride symbolism). Matches user intent for downloadable vector art, color reference, or attention-grabbing visuals.
