MONTHLY CHALLENGE // Iridescence

Added 2025-08-01 08:06:48 +0000 UTC

This month's challenge is on iridescence! That's the shimmering, rainbow-like effect that you can see on gemstones, bubbles, butterfly wings, and more. This is a great way to practice blending colors, and capturing different types of surfaces! It's also a great effect to use in your paintings. Maybe studying it will spark some ideas ✨
