ChatGPT vs DeepSeek: suggestions of diverging data color schemes

Comparing the ChatGPT and DeepSeek suggestions for a Pantone 2025 Color of the Year Diverging Color Scheme.

Here, I compare ChatGPT and DeepSeek approaches to generating a customized diverging data color scheme that includes Mocha Mousse, the Pantone 2025 Color of the Year. Pantone provides suggested color harmonies but does not build data color schemes for its hues. I specifically asked both Gen AI systems to “Specify a five class diverging color scheme for Mocha Mousse with a neutral — white midpoint and color hex codes that passes color deficiency tests.”. Let’s begin this writing by reviewing the diverging data color scheme, color deficiency, and the Pantone Color of the Year concepts.

A Diverging Data Color Scheme:

Diverging data color schemes are created by joining two sequential color sequences together with a neutral midpoint. The data color scheme is often used for data that include a critical midpoint value (the mean, median or zero value) and a data distribution with two ends of importance. Below I show two listings of generic diverging color schemes, one from ChatGPT and the other from DeepSeek. Both Gen AI systems provided a series of color Hex code solutions based on my prompt: “Create various diverging color scheme suggestions”. For those unfamiliar with the concept, a color Hex code is a hexadecimal way to represent a color in RGB format by combining amounts of Red, Green, and Blue to note that specific color. Color Hex codes are not case-sensitive so #FFFFFF and #ffffff equally represent the color White. In a prior UX Collective writing, I described how I used the Adobe Color app to visually depict color Hex code specified data color schemes.

Addressing Color Deficiency:

As noted in my prior UX Collective and Nightingale writings on color, humans have three types of photoreceptors or cones. Each is sensitive to different parts of the visual spectrum of light to facilitate rich color vision. A red cone deficiency is classified as Protanopia. A green cone deficiency is classified as Deuteranopia. A blue cone deficiency is classified as Tritanopia. Software is available that simulates color deficiencies.
