Field's Purple Or Purple Rubiate Is The Only Durable Organic
:
ON THE SECONDARY, PURPLE.
purple the palette possesses. Marked by a soft subdued richness rather
than by brilliancy, it leans somewhat towards marrone, and affords the
greatest depth of shadow without coldness of tint. Unfortunately, in the
whole range of artistic pigments there is no colour obtainable in such
small quantity as madder purple; hence its scarcity and high price cause
it to be confined to water-colour painting, in which the clearness and
beauty of its delicate tones render it invaluable in every stage of a
drawing. With raw Sienna and indigo or Prussian blue, subdued by black,
it gives beautiful shadow tints, and will be found useful in sky and
other effects compounded with cobalt, rose madder, French blue and
sepia, yellow ochre and cobalt, lamp black and cobalt, light red,
Vandyke brown, burnt Sienna, or aureolin. With great transparency, body,
and depth, it is pure and permanent in its tints, neither gives nor
sustains injury on admixture, dries and glazes well in oil, works well,
and is altogether most perfect and eligible. For fresco it is admirably
adapted, being quite uninjured by lime.
There is a lighter and slightly brighter sort, containing less colouring
matter and more base, which has all the properties of the above with
less intensity of colour. For the sake of cheapness, the purple is
sometimes compounded in oil, generally of brown madder and a blue.
Provided the latter be stable, transparent, and mix kindly, no greater
objection can be taken to this than to the neutral orange of brown
madder and yellow ochre.
