bro·mine (brō'mēn)
n. (Symbol Br)
A heavy, volatile, corrosive, reddish-brown, nonmetallic liquid element, having a highly irritating vapor. It is used in producing gasoline antiknock mixtures, fumigants, dyes, and photographic chemicals. Atomic weight 79.904; atomic number 35; melting point 7.2°C; boiling point 58.78°C; valence 1, 3, 5, 7.
A chemical element, Br, atomic number 35, atomic weight 79.909, which normally exists as Br2, a dark-red, low-boiling but high-density liquid of intensely irritating odor. This is the only nonmetallic element that is liquid at normal temperature and pressure. Bromine is very reactive chemically; one of the halogen group of elements, it has properties intermediate between those of chlorine and iodine. See also Halogen elements; Periodic table.
The most stable valence states of bromine in its salts are ?1 and +5, although +1, +3, and +7 are known. Within wide limits of temperature and pressure, molecules of the liquid and vapor are diatomic, Br2, with a formula weight of 159.818. There are two stable isotopes (79Br and 81Br) that occur naturally in nearly equal proportion, so that the atomic weight is 79.909. A number of radioisotopes are also known.
The solubility of bromine in water at 20°C (68°F) is 3.38 g/100 g (3.38 oz/100 oz) solution, but its solubility is increased tremendously in the presence of its salts and in hydrobromic acid. The ability of this inorganic element to dissolve in organic solvents is of considerable importance in its reactions.

Bromine is a chemical element in the periodic table that has the symbol Br and atomic number 35. A halogen element, bromine is a red volatile liquid at standard room temperature which has a reactivity between chlorine and iodine. This element is corrosive to human tissue in a liquid state and its vapours irritate the eyes and throat. Bromine vapours are very toxic upon inhalation.

Ah you missed one Iodine ! Well purple is sort of red.
But nitric fumes the most (more brown - the color of smog), bromine too (though still brownish) both qualify.
Hey to get a really red fume how about combining bromine and iodine in the same bottle.

i'm not even going to tell you as this is the key ingredient in binary explosives and i doubt your motives.
