What is the difference between pigments and light refraction?

I would like to share few interesting facts about the Blue morpho butterflies. Probably this would give a clear picture about how these butterflies use the advantage of light's refraction property to product vibrant colors. read more

Iridescent color comes from light refraction and changes with the angle of the light as it stricken the object (pearls and other natural objects have this characteristic). By comparison pigments tend to be flat and uniform in color. read more

Key Differences Between Reflection and Refraction. The points presented below are substantial, so far as the difference between reflection and refraction is concerned: The reverting of light or sound waves in the same medium, when it falls on the plane, is called reflection. read more

Luminous objects give off their own light; like the sun. Illuminated objects only reflect light; like the moon. read more
