Classic Rainbow Illustration - Colorful Arc for Design & Education #229086 (License: Personal Use)

This illustration features a classic seven-band rainbow (ROYGBIV) drawn with bold, slightly irregular strokes that evoke a hand-painted or marker-style aesthetic. The vivid colors stand out sharply against the solid black background, enhancing contrast and visual impact. Its simplicity and emotional resonance make it suitable for both digital and print applications.

Commonly used in educational materials (e.g., teaching color theory or weather), LGBTQ+ pride resources, children’s books, websites promoting positivity or inclusion, and as a decorative element in UI/UX design where symbolism of hope or unity is desired.
