Minus the contextual thing... colors are monoidal under RGB. Its a 3 dimensional vector with all the properties of numbers. All of this is because our eyes have 3 color detectors, RGB. The reality is, RGB is just a mapping. Actual color is a singular number scalar based off the wavelength of light. So colors are actually a GOOD choice for number representation. The real question is how do colors compose in your brain? If you encountered two numbers 8 and 9. Could you add those numbers just thinking in terms of colors? What about for large numbers, there must be large enough numbers where no color mapping exists as colors have limited range in our spectrum of vision. How does your brain picture 9999999999999999999999? Even if it's contextual if your brain follows consistent logic during composition of numeric entities it's still a valid analogy. The can opener number 9 just seems completely over engineered.
