If a reducing sugar is present a precipitate of this color is formed by Benedict's and Fehling's tests, and it is the color of selenium crystals and liquid sulfur di-chloride.
If the carbonyl compound is aromatic, then the precipitate will be this color in a positive Brady's test. If a reducing sugar is present a precipitate of this color is formed by Benedict's and Fehling's tests, and it is the color of selenium crystals and liquid sulfur di-chloride. The allotrope of (*) phosphorous with this color is made of amorphous interlocking tetrahedra, and the lower range of an indicator made from lichen dyes is this color. Performing the flame test on cadmium, lithium, and strontium gives this color, and it's present in minerals containing iron-three ions like ferric oxide. For 10 points, name this color given off by rust and the dust on Mars.
