    An occurrence of altocumulus and cirrocumulus cloud iridescence Sunset reflecting shades of pink onto grey stratocumulus clouds. The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum.

  5. Noctilucent cloud - Wikipedia

    en.wikipedia.org/wiki/Noctilucent_cloud

    Noctilucent clouds form mostly near the polar regions, [7] because the mesosphere is coldest there. [15] Clouds in the southern hemisphere are about 1 km (3,300 ft) higher than those in the northern hemisphere. [7] Ultraviolet radiation from the Sun breaks water molecules apart, reducing the amount of water available to form noctilucent clouds.

    In a technique known as blue field entoptoscopy, the effect is used to estimate the blood flow in the retinal capillaries.The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture to the perceived entoptic dots.
