"Given the challenge that the Claude chatbot faced in specifying a perceptual uniform Triad color harmony that passes color deficiency, I decided to explore how ChatGPT-5 might handle this request. ChatGPT-5 provided a straightforward solution that works in both traditional and perceptual uniform color spaces. I describe this amazing solution here. Let's begin our journey by first defining the concepts of a triad color harmony, perceptual uniformity and color deficiency. From there, the ChatGPT-5 color suggestion can be examined in detail."
"The Triad Color Harmony: Color harmony is the process of choosing colors on a color wheel that work well together in the composition of an image. Like concepts in music, these harmonies are based around color combinations on the color wheel that help to provide common guidelines for how color hues will work together. Isaac Newton is credited with creating the color wheel concept when he closed the linear color spectrum into a color circle in the early 1700s."
A triad color harmony uses three hues spaced 120 degrees apart on a color wheel to produce balanced palettes. Color wheels derived from RYB (painter's) and RGB (display) color spaces yield different triad results. Isaac Newton closed the linear color spectrum into a circular wheel in the early 1700s, forming the basis for later artistic and scientific refinements. Perceptual uniformity requires colors to be spaced so perceived differences match numerical distances, while color-deficiency constraints require distinguishability for viewers with common color-vision deficiencies. ChatGPT-5 provided a triad solution that functions in both traditional and perceptual-uniform color spaces.
