Art Supplies Online: Pigments |
|||||
Choosing the Right PigmentsRather than grapple with the vast range of pigments available today, particularly through art supplies online, painters will generally make better headway by getting to know a small number of pigments that meet most requirements. Ideally, the selection should be based on:
Some General AdviceWhitesTitanium white dries fast, and is the most opaque. Flake white is the quickest drying, but discolors if not protected by oil. Zinc white gives the purest color mixes but is only half opaque, dries slowly and will crack if applied too thickly. Dead coloringFor blocking out large areas of a canvas prior to more detailed painting, the following are colour-fast, generally cheap (except the cadmiums), and have good covering power: ivory black, flake white, Indian red, yellow ochre, Naples yellow light, cadmium light red and yellow, emerald green and Sevres blue. GlazesPigments in glazes need to be colour-fast and transparent. Dutch vermilion, Rembrandt rose, ultramarine deep, Rembrandt blue, gold ochre, raw sienna, lemon yellow, terre verte, burnt umber, raw umber and Rembrandt green are the traditional favorites. Many have been replaced by pigments listed below. Dutch vermilion, lemon yellow and zinc white are only half transparent. Paint Strength Grouped by Drying TimesBazzi (see below) provided this grouping: RapidUmbers: tough & flexible. Aureolin: hard & erratic. Burnt sienna: hard & fairly strong. Flake white hard & flexible AverageCerulean fairly flexible Raw sienna: tough & fairly strong. Cobalt blue: hard & fairly brittle. Cobalt violet: rather brittle. Red iron oxide: strong Chromium oxide: flexible & fairly hard. Viridian: flexible & fairly hard. Naples yellow: strong. Quinacridones (permanent rose & magenta, rose doré) hard & fairly flexible SlowGreen earth: soft & flexible. Cerulean: soft & non-elastic. Yellow ochre: fairly strong. Alizarin: soft. Ivory black soft & brittle Cadmiums hard & fairly flexible Titanium white brittle Very SlowIvory black: soft Zinc oxide: hard & brittle. Lamp black: soft. PermanenceTesting by Wilcox (see below) has suggested that many watercolor (and by extension oil) paints may be unsatisfactory fugitive, badly blended, with poor spreading and transparency. Exceptions pigments that are worth selecting from art supplies online include the following. (T is Talens, R is Rowney and WN is Windsor and Newton. Unless otherwise indicated, all are first artists's quality. The order does not matter, though Wilcox prefers WN to the more oily T.) Grouped by transparency, the recommended pigments are: :Transparent ColorsAureolin (R and WN) Permanent rose (WN and R) Permanent magenta (WN) Scarlet lake (WN) Cobalt blue (R and WN) Ultramarine (WN and T and R and Georgian) Viridian (R and T) Light red (WN and R and T) Gold ochre (T) Burnt sienna (WN and R and T) Burnt umber (Georgian and T and WN) :Opaque ColorsNaples yellow (R and WN and T) Cadmium yellow Light (R and T and WN) Cadmium yellow (WN and R and T) Cadmium orange (R - I have WN now) Cadmium red (R and T and WN) Cadmium red Deep (WN) Cerulean blue (R and WN and T) Chromium oxide Green (WN) Indian red (WN and R) Yellow ochre (Georgian and WN and R) Raw umber (Cotman and WN and R and Reeves) Ivory black (R and WN and Cotman>>Georgian) DiscolorationBazzi warns that discoloration occurs with these mixtures: Cerulean with Indian red or ivory black. Light cadmium yellow with red earths or cobalt violet. Medium cadmium yellow with raw & burnt earths, also cobalt violet. Cadmium orange with burnt sienna. Ultramarine with aureolin. Ultramarine with zinc white (fades). Grounds with red or brown earths, especially with oils, absorb mid-shades of overlying paint and darken. Viridian and cadmium yellow are stable only in zinc white. Naples yellow and cobalt violet are discolored by a metal spatula. CostsPigments vary greatly in price, as a glance at the colorman's or art supplies online catalogue will show. ReferencesThe republication of artists's reference works has become quite an industry, and these books are certainly essential to the art restorer. Nonetheless, no professional oil painter should be without one of the first three. Wilcox has useful information on color permanence, equally disturbing to the oil painter.
