Synthetic dyes are created through chemical processes and can mimic a wide range of colors found in nature, including orange.
The Chemistry of Color
The perception of color is a result of how our eyes and brain interpret light. When light hits an object, some of that light is absorbed, and the rest is reflected. The reflected light is what gives an object its color. In the case of food coloring, dyes absorb certain wavelengths of light and reflect others, which our eyes perceive as color. The unique combination of absorbed and reflected wavelengths determines the color we see.
The Quest for Orange: Unraveling the Dye Combination
Orange, being a blend of red and yellow, requires a specific combination of dyes to achieve its distinctive hue. The exact formulation can vary depending on the desired shade of orange, the type of food product, and whether natural or synthetic dyes are used.
