The linear nature of color matching is critical to maintaining color accuracy and predicting how colors will translate between different media. I suspect this principle would be particularly useful in the fields of digital image processing, display technology development, and professional printing. It ensures that we are able to create the desired hue by mixing the correct colors, and when color correcting, the color can be accurately predicted and replicated.

It is interesting that color matching is linear, even though so many aspects of human sensory data is on a log scale (e.g. we perceive the brightness of light and the loudness of sound logarithmically).
