Prompt

Apply a Color Negative effect, reversing every red, green, and blue channel so highlights become dark, shadows become light, and colors turn into their exact complements. Render uncanny cyan, magenta, and yellow relationships while retaining sharp detail and smooth texture. Keep the original subject and composition.

Identify

Light colors become dark and complementary colors emerge.

Principle

Each channel value1 is subtracted from its maximum.

Try it out

Compare red and orange after inversion2.

Classification

Calculated image processing result.
