👉 Heterochromatic is a term in physics that describes an object with two colors of light. It refers to objects that are not symmetric, meaning they have different brightnesses or color differences from each other when viewed under different conditions or at different wavelengths. In contrast, homochromatic is a term describing objects that are symmetrically colored, meaning they have the same brightness or color difference for all wavelengths. For example, an object might be both heterochromous and homochromatic.
