Pigments and Paints: What you make art with
The Stuff of Paint
Watercolor: What it is.


Gum Arabic Crystals
Traditional transparent watercolor is finely ground pigment in a water-soluble binder such as gum arabic. Gum arabic is water-soluble gum produced by a species of the acacia tree and is available in crystalline form or in prepared solutions. The gum arabic crystals or granules are transparent when pure, but less highly refined varieties can be yellowish to honey colored. Gum arabic is also used in inks, adhesives, pharmaceuticals, and confections (it's non-toxic and tasteless).
Other binders used for watercolor paint have included Tragacanth, a gum optained from various asian shrubs, and fish glue. Glycerine, dextrin, crystallized sugar, syrup, or honey can be added to modify the working texture of the paint, counteracting the brittle quality of the gum arabic a bit. Ox gall can be added as a surfecant or wetting agent to aid the free flow of washes. (Think dishwasher soap's "sheeting action") Oil of cloves can be added to deter the growth of molds which can happen on cheap quality paints.

Which water?

Distilled or boiled water are said to give the best results when painting, avoiding adulterants that may affect certain pigments. I use tap water.

On Student Grades and cheaper paints

Cheaper paints tend to have excess binder that can result in a glossy sheen in a finished wash of color. Student grade paints use less refined pigments mixed with a neutral filler pigment. Some manufacturers offer "hues" of a color such as "cobalt blue hue" or "manganese blue hue". These are mixed using a less expensive pigments, Ultramarine Blue and Pthalocyanine Blue in this case, to simulate the more expensive genuine color. They are a cheaper way to go but their tinting strength is generally poor compared to the "real" pigments. You can learn to mix your own "hue" colors from a rather limited palette.




The Ark of
the Covenant


An Acadia Wood Ark of the Covenant
Designed to a T.

Religion 101:

Did you know the Ark of the Covenant was said to be fashioned of acacia wood?
(Exodus 25:10)

Acadia wood is the dense, fine-grained wood with a beautiful orange color that also happens to bear forth gum arabic.



Watercolor pigments are classified in two groups:

INORGANIC (Mineral) ORGANIC

  1. Native earths: ochre, raw umber, etc.

  2. Calcinated native earths: burnt umber, burnt sienna, etc.

  3. Inorganic synthetic colors: cadmiums, zincs, etc.

  1. Vegetable: gamboge, indigo, madder, etc.

  2. Animal: cochineal, Indian yellow, etc.

  3. Synthetic organic pigments

Color List
New pigments and dyes are formulated constantly. The following list, while not complete, illustrates the wide variety of colors currently available today. When direct information on the color isn't available a best guess was made based on the name of the color and that name's traditional use by artists. For complete toxicity information always check the manufacturer's label. You are viewing digital approximations of real watercolor hues, so look at the manufacturer's color chart before you buy.

Proprietary Names
Manufacturers sometimes assign their own names to standard pigments or mixtures of standard pigments. This can get confusing when you have to buy a certian color but your favorite brand is not available. Always read the manufacturer's content labels to find out what you are actually purchasing.

Blockx:
  • Blockx Blue (Phthalocyanine blue)
  • Blockx Green (Phthalocyanine green)
  • Blockx Red (Toluidine red)
  • Blockx Yellow (Arylide yellow)
Grumbacher:
  • Grumbacher Red (napthol red)
  • Thalo Blue (Phthalocyanine blue)
  • Thalo Crimson (Quinacridone violet)
  • Thalo Green (Phthalocyanine green)
  • Thalo Purple (Dioxazine purple and ultramarine blue)
  • Thalo Red (Quinacridone violet)
  • Thalo Yellow Green (Arylide yellow and phthalocyanine green)
Winsor & Newton

Transparent Colors
Transparent colors appear more intensely hued when laid on white paper. They are excellent for working in layered washes where the transparent qualities can create jewel-like tones. You can only glaze and tint darker washes with a transparent color. Whatever is underneath will show through.

Transparent colors include:
Phthalocyanine blue, phthalocyanine green, phthalocyanine green, phthalocyanine violet, scarlet lake, rose madder, permanent rose, new gamboge, Hooker's green, cyanine blue, indian yellow, coral.



Opaque Colors
Care must be used when using opaque pigments in transparent watercolor painting. Using Opaque colors on top of other washes can result in a chalky appearance and can muddy up underlying colors. They are good for initial washes on white paper, in mixtures, creating skin tones, and accenting a painting.

Opaque Colors include: Cadmium Yellow, cadmium red, cadmium orange, venetian red, yellow ochre, emerald green, cerulean blue, naples yellow.



Reflective Colors
Due to their innate molecular structure, reflective pigments are rather chalky and tend to "ride the surface" of a painting. This is true physically as well as visually. I've found the cobalt family to be difficult to record accurately with a digital camera. What looks fine to the naked eye can be reflected back into the camera with greater luminosity than other colors in your painting.

Reflective colors include: Cobalt violet, cobalt blue, raw sienna, viridian green, aureolin yellow.



Sedimentary Colors
The materials of these pigments have a higher specific gravity than other pigments. This added weight will cause washes using these pigments to settle out into the texture of your paper, creating a texture of their own. The heavier pigments have a coarser grind due to their nature. Many are from the clays and stones beneath our feet.

Sedimentary colors include: Ultramarine blue, raw sienna, raw umber, sepia, cobalt violet, cobalt blue, viridian green, manganese blue, sap green.



Staining Colors
Man-made dye-based pigments stain your paper the most. Many are intense in hue and have a proven track record for greater permanence. In general, mineral based, and natural plant and earth pigments have less staining power.

Heavy Staining Colors: Phthalocyanine blue, phthalocyanine green, phthalocyanine violet, dioxazine purple (Winsor violet), alizarin crimson, scarlet lake, sap green, Hooker's green.

Light Staining Colors: Gold Ochre, raw umber, cadmium orange, cobalt blue, gamboge yellow, cerulean blue, magenta.

Non-Staining Colors: Emerald green, permanent rose, manganese blue, aureolin yellow, cobalt violet.



Fugitive Colors

The pigments in the "fugitive" class of paints have the unfortunate characteristic of looking beautiful and unique when first painted but show bad side-effects over time. Side effects include fading to non-existence, changing color, darkening to black, and other fun stuff. Many in this class of colors were organic plant materials first used to make pigment for watercolor paints, like the madders. Unless you're planning on hermetically sealing your paintings and viewing them in a low-UV climate controlled room, skip them. Use paints with lightfast ratings I or II (AA or A) when possible.


Tube and Pan Sizes
Being as there is no real set standard for tube sizes they can vary in size from 5 ml up to 37 ml and more. Liquid watercolors also have a wide range of product sizes and strengths. I've always looked at them as small (5-8ml) and large (10-15ml) and "Should I be painting more?" (21ml and larger)

A variety of makers and sizes
Brands and General Sizes: Blockx 15ml; DaVinci 37ml; Grumbacher 7.5ml; Holbein 15ml-#5; Rowney 15ml; Rembrandt (Talens) 5ml; Schmincke Horadam 5ml-#2, 15ml-#6; Sennelier 10ml; Van Gogh 10ml; Winsor & Newton Cotman 8ml, 21ml; Winsor & Newton Artist's 5ml-#2, 14ml-#5;

Approximate Pan Weights and Sizes:
Half Pan: 1.5ml - 1/2" x 5/8" x 1/4"
Full Pan: 3ml-4ml - 1" x 5/8" x 1/4"
