"Sulfur dye Sulfur dyes are the most commonly used dyes manufactured for cotton in terms of volume. They are cheap, generally have good wash-fastness, and are easy to apply. Sulfur dyes are predominantly black, brown, and dark blue. Red sulfur dyes are unknown, although a pink or lighter scarlet color is available. The forerunner of sulfur dyes is attributed to ""Cachou de Laval,"" which is prepared by treating wood products with sulfide sources. Subsequently, the so-called Vidal Blacks were produced by reactions of various aniline derivatives with sulfur. These experiments demonstrated that deeply colored materials could be readily produced by"

As with most colours, there is no absolute definition of its exact hue, but according to Etymology Online, ""powder blue"" originally referred in the 1650s to powdered smalt (cobalt glass) used in laundering and dyeing applications, and it then came to be used as a colour name from 1894. Although smalt itself is a deep, dark blue hue, powder blue is nowadays depicted as more of a pale cobalt blue as illustrated by the examples below, which show powder blue as defined by British and Australian Standards for paint colours"
"Sapphirine Sapphirine is a rare mineral, a silicate of magnesium and aluminium with the chemical formula (Mg,Al)(Al,Si)O (with iron as a major impurity). Named for its sapphire-like colour, sapphirine is primarily of interest to researchers and collectors: well-formed crystals are treasured and occasionally cut into gemstones. Sapphirine has also been synthesized for experimental purposes via a hydrothermal process. Typical colours range from light to dark sapphire blue, bluish to brownish green, green, and bluish or greenish gray to black; less common colours include yellow, pale red, and pink to purplish pink. Sapphirine is relatively hard (7.5 on Mohs scale), usually"

Vermilion is not one specific hue; mercuric sulfides make a range of warm hues, from bright orange-red to a duller reddish-purple that resembles fresh duck liver. Differences in hue are caused by the size of the ground particles of pigment. Larger crystals produce duller and less-orange hue. Cinnabar pigment was a side-product of the mining of mercury, and mining cinnabar was difficult, expensive and dangerous, because of the toxicity of mercury. The Greek philosopher Theophrastus"

Mercury(I) sulfate is a metallic compound that is white, pale yellow or beige powder. It is a metallic salt of sulfuric acid formed by replacing both hydrogen atoms with mercury(I). It is highly toxic; it could be fatal if inhaled, ingested, or absorbed by skin. The crystal structure of mercurous sulfate is made up of Hg dumbbells and SO anions as main building units. Hg dumbbell is surrounded by four Oxygen atoms with Hg₋O distance ranging from 2.23 to 2.93 Å, whereas"

Sudan I has also been adopted for colouring various foodstuffs, especially curry powder and chili powder, although the use of Sudan I in foods is now banned in many countries, because Sudan I, Sudan III, and Sudan IV have been classified as category 3 carcinogens (not classifiable as to its carcinogenicity to humans) by the International Agency"
"MPa) is injected into the deposit via the outermost tube. Sulfur (m.p. 115 °C) melts and flows into the middle tube. Water pressure alone is unable to force the sulfur into the surface due to the molten sulfur's greater density, so hot air is introduced via the innermost tube to froth the sulfur, making it less dense, and pushing it to the surface. The sulfur obtained can be very pure (99.7 - 99.8%). In this form, it is light yellow in color. If contaminated by organic compounds, it can be dark-colored; further purification is not economic, and usually unnecessary. Using"

The basic palette for patinas on copper alloys includes chemicals like ammonium sulfide (blue-black), liver of sulfur (brown-black), cupric nitrate (blue-green) and ferric nitrate (yellow-brown). For artworks, patination is often deliberately accelerated by applying chemicals with heat. Colors range from matte sandstone yellow to deep blues, greens, whites, reds and various blacks. Some patina colors are achieved by the mixing of colors from the reaction with the metal surface with pigments added to the chemicals. Sometimes the surface is enhanced by waxing, oiling,"
"sulfur deposited by fumaroles formed such flows. Some fumaroles currently release centimetre-long sulfur flows. Flows of sulfur are highly fragile constructs that can easily be destroyed. The conditions surrounding the emplacement of the sulfur have caused the sulfur to assume various colours, including black, brown-orange, orange, red, yellow, and yellow-orange. These colours vary along the length of the flows and between various flows, indicating that temperatures varied between one flow and another. Liquid sulfur has different viscosity and rheomorphic properties at different temperatures, and some variation occurred at Lastarria's flows as well. Such sulfur flows are rare on Earth; they"
"Sulfuric acid Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula HSO. It is a colorless, odorless, and syrupy liquid that is soluble in water, in a reaction that is highly exothermic. Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapor from the air. Upon contact, sulfuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even"
"Purple sapphires contain trace amounts of vanadium and come in a variety of shades. Corundum that contains ~0.01% of titanium is colorless. If trace amounts of iron are present, a very pale yellow to green color may be seen. However, if both titanium and iron impurities are present together, and in the correct valence states, the result is a deep-blue color. Unlike localized (""intra-atomic"") absorption of light which causes color for chromium and vanadium impurities, blue color in sapphires comes from intervalence charge transfer, which is the transfer of an electron from one transition-metal ion to another via the conduction"

Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant"

When exposed to oxygen, white phosphorus glows in the dark with a very faint tinge of green and blue. It is highly flammable and pyrophoric (self-igniting) upon contact with air. Owing to its pyrophoricity, white phosphorus is used as an additive in napalm.

"Sulfur tetrafluoride Sulfur tetrafluoride is the chemical compound with the formula SF. It is a colorless gas. It is a corrosive species that releases dangerous HF upon exposure to water or moisture. Despite these unwelcome characteristics, this compound is a useful reagent for the preparation of organofluorine compounds, some of which are important in the pharmaceutical and specialty chemical industries. Sulfur in SF is in the formal +4 oxidation state. Of sulfur's total of six valence electrons, two form a lone pair. The structure of SF can therefore be anticipated using the principles of VSEPR theory: it is a see-saw"
