| A Hindu Tale The Jackal stood looking across the river where the crabs lay in the sun on the sand. "Oh," said the Jackal, "if I could only swim, how good those crabs would be! I wish I had a boat or a canoe!" Just then the Camel came ... Read more of The Jackal And The Camel at Children Stories.ca | InformationalPrivacy |

Purple Being A Secondary Colour Composed Of Blue And Red Itfollows of course that any blue and red pigments, which are not chemically at variance, may be employed in producing mixed purples of any required hue, either by compounding or grinding them together ready for use, or by combining them in the various modes of operation in painting. In such compounding, the more perfect and permanent the original colours are, the more perfect and permanent will be the purple obtained. To produce a pure purple, neither the red nor the blue must contain or incline to yellow; while to compound a durable purple, both the red and the blue must be durable also. Ultramarine and the reds of madder yield beautiful and excellent purples, equally stable in water or oil, in glazing or tint, whether under the influence of light or impure air. Cobalt blue and madder red likewise afford good purples; and some of the finest and most delicate purples in ancient paintings appear to have been composed of ultramarine and vermilion, which furnish tints equally permanent, but less transparent than the above, and less easily compounded. Facility of use, and other advantages, are obtained at too great a sacrifice by the employment of perishable mixtures, such as the lakes of cochineal with indigo. PERMANENT REDS. PERMANENT BLUES. Cadmium Red. Cerulian Blue. Liquid Rubiate. Cobalt Blue. Madder Carmine. Genuine Ultramarine. Rose Madder. Brilliant Ultramarine. Mars Red. French Ultramarine. Ochres. New Blue. Vermilions. Permanent Blue. It should be noted that all the above reds do not afford pure purples with blue; those which contain more or less yellow, as cadmium red and orange vermilion, furnish purples partaking more or less of olive, which is a compound of purple and green. To those reds may be added the russet Rubens Madder and the marrone Madder Brown, two pigments which are alike eligible for mixed purple and mixed orange. No purple, it will be remarked, equal in gorgeous richness to that produced from crimson lake and Prussian blue is obtainable from the colours given; just as no mixed green is of such depth and power if that blue be wanting as a constituent. But, as our compound tints are given rather as examples of durability than beauty, all semi-stable or fugitive mixtures are of necessity ignored.
