"description": "The color of blood depends on its oxygen level. When there is plenty of oxygen, the color is a brighter red. The reason is because of a protein called hemoglobin, which carries the oxygen in your blood. When hemoglobin has a full oxygen load, it has a bright red color, and when it's deoxygenated it's a darker red. For example, arterial and capillary blood is bright, and venous blood is dark.",

Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general \"copper alloy\".",

"description": "Modern car paints are nearly always an acrylic polyurethane \"enamel\" with a pigmented basecoat and a clear topcoat. It may be described as \"acrylic\", \"acrylic enamel\", \"urethane\", etc. and the clearcoat in particular may be described as a lacquer. The size of the metal flakes in metallic paints is typically between 100 to 400 microns in diameter. Modern automobile paint is applied in several layers, with a total thickness of around 100 μm (0.1mm).",

Nacre is the material of which pearls are composed and consists of aragonite crystal layers separated by conchiolin, a protein secreted by mollusk shells. The thickness of these layers determines the color of reflection from the nacre. The transmission interference color is complementary to the reflection interference color.",
