    Area of Science:

    • Develops a novel mathematical framework for understanding color vision.
    • Explores the algebraic structure underlying human color perception.

    Context:

    • Addresses the need for a unified mathematical model of color vision.
    • Investigates the relationship between established color vision theories, such as Young-Helmholtz and Hering.

    Purpose:

    • To develop an algebra of color vision analogous to spinor algebra.
    • To represent colors using complex numbers, where intensity is the modulus and hue is the phase.
    • To demonstrate the mathematical equivalence of different color vision models.

    Summary:

    • Introduces a complex number-based algebra for color vision, where white is zero.
    • Color intensity is mapped to the modulus and color hue to the phase of complex numbers.
    • Shows that both Young-Helmholtz and Hering models yield the same complex number algebra.

    Impact:

    • Provides a new mathematical perspective on color perception.
    • Offers a unified approach to understanding different color vision theories.
    • Potential applications in color science, computer vision, and display technologies.
