I was told that the color of honey contains so much chemistry and that was interesting to me and after doing a couple of research I found that the color of honey depends on the presence of plant pigments including carotene, xanthophylls, anthocyanins, flavonoids, polyphenols, as well as amino acids and mineral salts. So as we can see there are many factors to the color of honey but my question is which out of all of the listed above is the main contributor and is the most affected by the increase in temperature (for example for acidity the main contributor is gluconic acid).

Yes, you are right about that. The color differences is due to the difference in levels of minerals, anti-oxidants, and other trace elements that are present. In particular, levels of polyphenols, flavonoids, and carotenoid have been observed to have high correlation with color. Polyphenols are found in high concentration in darker honeys, whereas flavonoids are found in higher concentrations in lighter honeys.
