Watercolor is a painting technique created by applying water-diluted pigments onto specially prepared papers. In this technique, the amount of water, the density of the paint, and the contact of the brush with the paper directly affect the appearance of the result. Watercolor requires careful planning as it is difficult to undo mistakes, but when applied with the correct techniques, it produces light, natural, and vibrant results.
Basic Characteristics of Watercolor
-
Transparency: The paint allows light to reflect off the paper surface. This gives the colors a natural luminosity.
-
Layered structure: New layers can be added after each color layer dries. This allows for tonal transitions and depth.
-
Guiding rather than controlling: The natural flow of water is important in watercolor. The artist guides the paint rather than controlling it completely.
Watercolor is widely used in nature paintings, illustration, pattern design, and architectural drawings.
Materials Required for Watercolor
Choosing the right materials is crucial for a successful watercolor painting. Quality material preserves color accuracy and prevents the paper from deteriorating.
1. Watercolor Paper
Paper is the cornerstone of the watercolor technique. Choosing the wrong paper causes the paint to spread or warp on the surface.
There are three main types of watercolor paper:
-
Cold Press: Medium-textured, suitable for both details and general surfaces.
-
Hot Press: Has a smooth surface. Preferred for fine details and works supported by pen and ink.
-
Rough: Has a noticeably textured surface. Used in landscapes and works featuring broad brushstrokes.
Paper thickness should be at least 300 g/m². Cotton-content papers absorb water evenly and do not deform.
Paper Preparation:
Securing the paper with masking tape prevents it from buckling upon contact with water. Lightly dampening and drying the paper (stretching) before large works provides a smoother surface.
2. Watercolor Paints
Watercolor paints come in two forms: tube and pan.
-
Tube paints: More concentrated and ideal for large surfaces.
-
Pan paints: Practical for portability, suitable for small areas and sketches.
The quality of the paint depends on the pigment ratio. Professional series offer more intense and permanent colors. Cheap paints often contain low pigment, which can lead to a dull appearance in mixtures.
Color mixing tips:
-
Blue + Yellow = Green
-
Red + Yellow = Orange
-
Red + Blue = Purple
-
When mixing colors, add water first and then incorporate the pigment.
3. Watercolor Brushes
Brushes determine how water and paint are distributed on the surface. Each brush type serves a different function.
-
Round brush: Suitable for general use. Can be used for both large areas and details.
-
Flat brush: Effective for flat surfaces and sharp edges. Ideal for background transitions.
-
Liner brush: Used for details like thin lines, plant branches, and strands of hair.
-
Mop brush: Used for wetting large areas, background preparation, and wash techniques. Since it holds a lot of water, it provides homogeneous transitions.
Brush Care:
After use, brushes should be washed in warm water and dried with the bristles facing upward. Brushes with deformed tips negatively affect drawing control.
4. Palette and Water Containers
A porcelain or plastic palette can be used for mixing colors.
It is useful to have two separate water containers:
-
One for cleaning the brush,
-
The other for using clean water in mixtures.
Do not add too much water when mixing colors. Excessive water causes the pigment to disperse and the color to fade.
5. Additional Materials
-
Masking fluid: Used to protect areas you want to keep white.
-
Paper towel: For removing excess water from the brush or correcting mistakes.
-
Pencil: A hard (HB) pencil is preferred for outlining the composition.
-
Masking tape: Necessary for securing the paper.
Basic Watercolor Techniques
Watercolor works are created with techniques that change according to different surface preparations and water ratios.
1. Wet on Wet
The paper is dampened with water and the paint is applied to this surface.
Result: Soft transitions, natural mixtures.
Usage: Sky, sea, misty landscapes.
2. Wet on Dry
Paint is applied directly to dry paper.
Result: Distinct edges and clear lines.
Usage: Detailed botanical, architectural, or portrait works.
3. Glazing
Another tone is applied over a color once it has dried.
Result: Increased depth and tonal variation.
Usage: Color transitions, shading.
4. Dry Brush Technique
Excess water is removed from the brush and the paint is applied directly to the surface.
Result: Textured and rough appearance.
Usage: Tree bark, stone surfaces, fabric texture.
5. Salt Technique
Salt is sprinkled onto wet paint. The salt absorbs the water, creating patterned areas on the surface.
Usage: Starry skies, textured backgrounds.
Color Use and Light Balance
In watercolor painting, light is generally achieved through the whiteness of the paper. White paint is not used; bright areas are left unpainted.
Moving from light colors to dark is a fundamental rule for maintaining the direction of light.
When mixing colors:
-
Using tones from the same family (e.g., among warm colors) creates harmony.
-
Complementary colors (blue-orange, red-green) create striking contrast when used side-by-side.
Common Mistakes in Watercolor Works
-
Over-wetting the paper (buckling and pigment dispersion)
-
Not cleaning the brush sufficiently (distorting color mixtures)
-
Ignoring drying times between layers
-
Excessive pigment use (dulling the color)
-
Not planning for white spaces
Application Suggestions
-
Do small color trials before starting your work.
-
Use a separate trial paper for every new technique.
-
Plan the composition in advance to determine the direction of the light.
-
Make corrections with a second layer if necessary after the paint dries.
