I guess violet eyes are unusual, but I think they look the same from my viewpoint.

Around it were arranged, like the five points of a star, the other five brilliant balls; one being rose colored, one violet, one yellow, one blue and one orange.

The shapes and colours are extremely varied; bilaterally symmetrical forms are most frequent with red, blue or violet colours.

A pellet of potassium when thrown on water at once bursts out into a violet flame and the burning metal fizzes about on the surface, its extremely high temperature precluding absolute contact with the liquid, exce p t at the very end, when the last remnant, through loss of temperature, is wetted by the water and bursts with explosive violence.

The reaction may be written 2K+ 211 2 0= 2K0H+H2, and the flame is due to the combustion of the hydrogen, the violet colour being occasioned by the potassium vapour.

Analysis, &c. - All volatile potassium compounds impart a violet coloration to the Bunsen flame, which is masked, however, if sodium be present.

The emission spectrum shows two lines, Ka, a double line towards the infra-red, and Ka in the violet.

Operating on this beam with a second prism, he found that the homogeneous light was not dispersed, and also that it was more refracted the nearer the point from which it was taken approached to the violet end of the spectrum RV.

This confirmed his previous conclusion that the rays increase in refrangibility from red to violet.

If we compare the spectrum produced by refraction in a glass prism with that of a diffraction grating, we find not only that the order of colours is reversed, but also that the same colours do not occupy corresponding lengths on the two spectra, the blue and violet being much more extended in the refraction spectrum.

P. Leroux discovered that iodine vapour refracted the red rays more than the violet, the intermediate colours not being transmitted; and in 1870 Christiansen found that an alcoholic solution of fuchsine refracted the violet less than the red, the order of the successive colours being violet, red, orange, yellow; the green being absorbed and a dark interval occurring between the violet and red.

It is soluble in cold water, giving a violet solution, which turns green on boiling.

Its salts are reddish violet in colour, and give a characteristic absorption spectrum.

The order of the successive colours in all colourless transparent media is red, orange, yellow, green, blue, indigo and violet.

Its solutions in the alkaline iodides and in alcohol and ether are brown in colour, whilst in chloroform and carbon bisulphide the solution is violet.

Under artificial illumination many sapphires appear dark and inky, whilst in some cases the blue changes to a violet, so that the sapphire seems to be transformed to an amethyst.

When of pale yellowish-green colour the sapphire is called "oriental chrysolite," when greenish-blue "oriental aquamarine," when of brilliant green colour "oriental emerald," and when violet "oriental amethyst."

Chromic acid and its salts, the chromates and bichromates, can be detected by the violet coloration which they give on addition of hydrogen peroxide to their dilute acid solution, or by the fact that on distillation with concentrated sulphuric acid and an alkaline chloride, the red vapours of chromium oxychloride are produced.

Chromic salts are of a blue or violet colour, and apparently the chloride and bromide exist in a green and violet form.

Chromic chloride, CrC1 31 is obtained in the anhydrous form by igniting a mixture of the sesquioxide and carbon in a current of dry chlorine; it forms violet laminae almost insoluble in water, but dissolves rapidly in presence of a trace of chromous chloride; this action has been regarded as a catalytic action, it being assumed that the insoluble chromic chloride is first reduced by the chromous chloride to the chromous condition and the original chromous chloride converted into soluble chromic chloride, the newly formed chromous chloride then reacting with the insoluble chromic chloride.

The violet form gives a purple solution, and all its chlorine is precipitated by silver nitrate, the aqueous solution containing four ions, probably Cr(OH 2) 6 and three chlorine ions.

If the violet solution is allowed to evaporate slowly at ordinary temperatures the sulphate crystallizes out as Cr2(S04)3.15H20, but the green solution on evaporation leaves only an amorphous mass.

The green salt in aqueous solution, on stand- ing, gradually passes back to the violet form.

At that time monochromatic photographs of the sun were first made on Mount Wilson with the red (Ha) line of hydrogen, previous hydrogen photographs having been taken with H/3, Hy or HS in the blue or violet.

Speaking broadly, red is the colour for feasts of martyrs, white for virgins, violet for penitential seasons, &c.; no less than sixty-three different uses differing in details have been enumerated.

The priest, vested in a violet cope, prays that God may send His angel to hallow the ash, that it become a remedium salubre for all penitents.

Since the minimum deviation is least for the least refrangible rays, it follows that the red rays will be the least refracted, and the violet the more refracted, and therefore the halo will be coloured red on the inside.

The badge is the lily-hilted sword of St James, enamelled red with gold borders; the ribbon is violet.

In 1789 these three orders were granted a common badge uniting the three separate crosses in a gold medallion; the joint ribbon is red, green and violet, and to the separate crosses was added a red sacred heart and small white cross.

Aluminium is a white metal with a characteristic tint which most nearly resembles that of tin; when impure, or after pro longed exposure to air, it has a slight violet shade.

It may be recognized by the violet coloration it gives when added to a very dilute solution of potassium bichromate in the presence of hydrochloric acid; by the orange-red colour it gives with a solution of titanium dioxide in concentrated sulphuric acid; and by the precipitate of Prussian blue formed when it is added to a solution containing ferric chloride and potassium ferricyanide.

A piece of a large tile, and part of a glazed vase, have the royal titles and name of Menes, originally in violet inlay in green glaze.

Various colors were used; beside the old green and blue, there were purple, violet, red, yellow and white.

Occasionally, as in violet, a flower arises singly in the axil of an ordinary foliage-leaf; it is then termed axillary.

The salt is often grey, through bituminous matter or other impurity, and rarely green, blue or, violet.

To the eye, however, members of this group present a greater variety of colour than those of any other - yellow, brown, olive, red, purple, violet and variations of all these being known.

When heated in air it is readily oxidized, with the formation of a reddish or violet vapour.

Thallous chloride, T1C1, is readily obtained from the solution of any thallous salt, by the addition of hydrochloric acid, as a white precipitate similar in appearance to silver chloride, like which it turns violet in the light and fuses below redness into a (yellow) liquid which freezes into a horn-like flexible mass.

Hottonia (water violet) is a floating water plant with submerged leaves cut into fine linear segments.

Gallium is best detected by means of its spark spectrum, which gives two violet lines of wave length 4171 and 4031.

Another remarkable fact is that these substances yield coloured solutions in organic solvents; triphenylmethyl gives a yellow solution, whilst ditolylphenyl and tritolylmethyls give orange solutions which on warming turn to a violet and to a magenta, the changes being reversed on cooling.

The spectrum, which closely resembles that of a sunspot, is marked by flutings or bands of lines sharply bounded on the violet side and fading off towards the red.

They may be recognized by the brownish violet colour they impart to a borax bead when heated in an oxidizing flame.

The hexachloride, WC1 6, is obtained by heating the metal in a current of dry chlorine in the absence of oxygen or moisture, otherwise some oxychloride is formed; a sublimate of dark violet crystals appear at first, but as the hexachloride increases in quantity it collects as a very dark red liquid.

It turns dirty violet on exposure to air and light; in moist air it absorbs oxygen and forms an oxychloride.

In particular he revived and gave new force to the theory of colour-vision associated with the name of Thomas Young, showing the three primary colours to be red, green and violet, and he applied the theory to the explanation of colour-blindness.

The principal other plants which bear the name are the wallflower, Cheiranthus Cheiri, called wall-gillyflower in old books; the dame's violet, Hesperis matronalis, called variously the queen's, the rogue's and the winter gillyflower; the ragged-robin, Lychnis Flos-cuculi, called marsh-gillyflower and cuckoo-gillyflower; the waterviolet, Hottonia palustris, called water-gillyflower; and the thrift, Armeria vulgaris, called sea-gillyflower.

Fraunhofer, who defined the colours by means of the dark lines in the solar spectrum; and showed that the ratio of the dispersion of two glasses varied about 20% from the red to the violet (the variation for glass and water is about 50%).
