As a body is heated, it emits thermal radiation. According to Wien's displacement law, as temperature increases, the peak wavelength decreases; red has the longest wavelength in the visible spectrum and is therefore the first color seen.

When an object reflects all wavelengths of visible light equally, it appears white to the human eye.

Indigo, Orange, Yellow, and Green are all colors found in the natural rainbow spectrum (VIBGYOR). Pink is not a spectral color and does not belong in this group.

The blue color of the sky is caused by Rayleigh scattering of sunlight by the atmosphere. Without an atmosphere, there is no scattering, so the sky appears black.

According to Wien's displacement law, the color of a star is related to its surface temperature. Hotter stars emit more light at shorter wavelengths, making them appear blue.

When copper or its compounds are introduced into a flame, they emit a characteristic blue-green color. This is a standard result in flame tests used to identify metal ions in chemistry.

In standard cartography, shades of blue are used to represent water, with darker shades indicating greater depth.
