The dye, when mixed with water, modifies the refractive index — a measure of the way a substance bends light — of the aqueous part of the tissue to better match the index of proteins and fats in the tissue.
—Katie Hunt, CNN, 5 Sep. 2024
But tartrazine dye, through its powerful absorption of blue wavelengths of light, changes the refractive index of water to be much closer to that of fat, Hong says.

In such a universe, rulers and yardsticks would never be straight (solid objects would expand and shrink with the temperature gradient) while the refractive index would make light rays appear to travel in curves rather than lines.
—Quanta Magazine, 30 July 2024
Moreover, this universe features a refractive index — a measurement of how light rays bend — that is inversely proportional to the temperature.
—Quanta Magazine, 30 July 2024
