Why is the orange-blue combination so visually striking?
Updated Feb 2026
Orange and blue are complementary colors, meaning they sit directly opposite each other on the color wheel. When placed together, each color makes the other appear more vivid and saturated than it would alone. This is a fundamental principle of color theory that artists and designers have used for centuries. On a katana, this means the orange elements appear warmer and the blue elements appear deeper than either would in isolation, creating a sword with exceptional visual energy.
