Calculate how humans perceive similarity between different colours

Question

I\'m working on a site where users can describe a physical object using (amongst many other things) any color in the rgb 0-255 range. We offer some simplified palettes for e

Answer 1

This sounds like a prime example for a neural net based approach (if you are in an experimenting mode :) because it's about creating a decision rule that mimics Human perception. A neural net that has six inputs (r, r', g, g', b, b') and one output (is_similar) can be easily trained by using e.g. your own perception of similarity as the training source!
