Colour Swatch Training Tool

Discover how water absorbs light wavelengths at increasing depths with this essential training aid. This helpful tool displays how colours progressively fade as divers descend, making it an invaluable resource for teaching underwater photography, colour theory, and dive physics. Perfect for instructors, students, and enthusiasts who want to understand the optical principles that govern underwater visibility and image capture. A practical, hands-on demonstration of depth's impact on colour perception.
