Sulfur burning blue, a volcanic flame that never quite reaches the surface.
Blue Lava is a medium blue, close to navy.
It can be described as medium, moderate, dim and gloomy.
Set in white, because white reads best on it.
Blue lava, also known as, and simply referred to as blue fire or sulfur fire, is a phenomenon that occurs when sulfur burns. It is an electric-blue flame that has the illusory appearance of lava. Despite the name, the phenomenon is actually a sulfuric fire that resembles the appearance of lava, rather than actual lava from a volcanic eruption. The most well-documented of these fires occur on Indonesia's Kawah Ijen volcano, where they regularly burn.
Read on WikipediaLava is magma that has been expelled from the interior of a terrestrial planet or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C. Lava may be erupted directly onto the land surface or onto the sea floor or it may be ejected into the atmosphere before falling back down. The solid volcanic rock resulting from subsequent cooling of the molten material is often also called lava.
Read on WikipediaBlue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
Read on WikipediaLava is a color that is a purplish shade of red. It is named after the color of volcanic lava.
