This image has partial transparency (254 possible levels of transparency between fully transparent and fully opaque). It can be transparent against any background despite being anti-aliased. Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem.
However, some loose-jawed fish emit red and infrared light, and the genus Tomopteris emits yellow light. [ 34 ] [ 41 ] The most frequently encountered bioluminescent organisms may be the dinoflagellates in the surface layers of the sea, which are responsible for the sparkling luminescence sometimes seen at night in disturbed water.

An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue (apart from the area around the Sun which appears white because the light is not scattered as much). The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum.
Yellow combined with red symbolized heat and energy. A room painted yellow feels warmer than a room painted white, and a lamp with yellow light seems more natural than a lamp with white light. As the color of light, yellow is also associated with knowledge and wisdom. In English and many other languages, "brilliant" and "bright" mean intelligent.
Opacity depends on the frequency of the light being considered. For instance, some kinds of glass, while transparent in the visual range, are largely opaque to ultraviolet light. More extreme frequency-dependence is visible in the absorption lines of cold gases.
The 1877 design featured a yellow star on a blue background. The 1877 flag continued as the flag of the Congo Free State after the territory was recognized as an official possession of Leopold II at the Berlin Conference. After gaining independence from Belgium on 30 June 1960, the same basic design was maintained.
