The Art of Color Separation: How Understanding Light Can Elevate Your Design The Farnsworth effect is a phenomenon in which white light is split into its component colors using an image dissector, a device developed by physicist Harold Farnsworth in the early 20th century.
This process relies on the principles of wave theory and color vision, where differences in wavelengths and dispersive properties cause light to break down into distinct spectral bands.
When white light passes through a prism or is refracted by a lens, it separates into its constituent colors: red, orange, yellow, green, blue, indigo, and violet.
