As the paint dries the excess moisture of the bead runs back into the damp wash, creating the flow marks which we call blooms. Blooms will also occur if you drip wet paint or clean water into a semi-moist area of paint.
Watercolor Blooms or 'cauliflowers' (some call them as well), are irregular splotches and marks where very wet paint has been introduced into an area that is quite a bit dryer, but not Bone Dry.
This well-known watercolour weed happens when water (or wetter paint) is added to a semi-dry area of paint. The effect, which looks like a head of cauliflower, increases as the paint dries.
Every watercolor artist has experienced an accidental back run—when a drop of water creates a “bloom” in a freshly painted wash. But for painting leaves, flowers and trees, I like to use intentional back runs to create mottled color, a feeling of foliage and the appearance of uneven lighting conditions.
Charging is the act of loading another color into a wet or moist field. It is very much like wet into wet painting. You will note it produces a soft effect while the other swatches that are glazes have hard edges.
If your paint is too thick and the paint is too sticky it tends to spread unevenly creating streaks or blotches. When mixing your paint begin by making a puddle of water. Then pick up some color with a moist brush and mix into the clear water.
In this blog post, we are going to take a closer look at four beginning watercolor techniques. Wet-on-wet, wet-on-dry, dry-on-dry, and dry-on-wet. These methods are referring to the paper and brush.
While there are actually many techniques, three are considered the building blocks and are what most watercolour artists use consistently and frequently. These include 'wet on dry', 'wet on wet', and watercolour washes.
Bloom refers to a phenomenon which occurs on a varnished surface of a painting if kept in damp conditions. This results in dull and cloudy areas on top, or sometimes below the varnish. Blooming is basically a result of moisture building up on the painting.
Cold-pressed paper is the exact opposite of hot-pressed paper. The paper consists of loose cellulose fibers that are rolled over with cold metal slab hence the name cold-pressed paper. It is relatively smooth in texture but not as smooth as hot-pressed paper.
watercolour, also spelled Watercolor, pigment ground in gum, usually gum arabic, and applied with brush and water to a painting surface, usually paper; the term also denotes a work of art executed in this medium.
Underpainting is a technique in which the shadow areas are built up first. The body colour of the subject is painted in transparent layers above.
Layering also makes some types of painting more manageable, because you can focus only on the tone and forms rather than thinking about mixing exactly the right hue. For example many artists do this by layering primary colors on top of each other - yellow, then red, then blue.
ELEMENTS OF ART: The visual components of color, form, line, shape, space, texture, and value.
Wet on wet: wet paint is applied to wet paper, or added to a wash of fresh paint. This creates a fluid, fun and unpredictable effect. There is less control with a wet on wet technique. To try it, lay down clean water on the paper, then add watercolor paint to the wet areas.
Watercolours look bad when they are too opaque. So, strive to achieve the opposite, which are light and transparent layers. Watercolours look dull when they lack vibrancy. So, make sure you're regularly rinsing off your brush and mixing colours whose pigments compliment each other.
There are many reasons why your watercolours look muddy. Some common reasons are: You're not letting each layer dry before painting the next layer. You're applying too many unnecessary brushstrokes.
