Watercolor Mixing Tips: Achieve Natural Transitions Easily

Display
Continuing from last week's Dinosaur watercolor theme, I tried a few different green color combinations and found it challenging to make the changes subtle.
The following further understanding of the relationship between color brightness, color, interested friends together to look down Oh.
:: Primary color
In color science, a primary color is a primary color that cannot be derived by mixing other colors.
For watercolor pigments, this usually means red, blue and yellow (magenta, cyan and lemon yellow are also used).
:: Secondary colors
A color made by mixing two primary colors. Example:
- Yellow + Blue = Green
- Red + Blue = Purple
- Red + Yellow = Orange
Lemon yellow (greenish yellow) is used in the first row, blended with sky blue (greenish).
The second row uses warmer yellow tones and greens, so you'll notice that the greens in the upper and lower rows give us a slightly warmer feeling than the greens in the lower rows.
There are ready-made cadmium orange pigments in the market, the color is more vivid, if you want to maintain the color and brightness, you can choose the ready-made pigments.
● Unmixed pigments:
Colors extruded directly from the pigment strip, e.g., orange, purple, emerald green, etc.
These colors may be mixed by the manufacturer during the production of the pigments, but are not primary colors.
● What is color scale?
Chroma refers to the purity and saturation of a color, i.e., the vividness of the color.
- High Colorimetry: Colors that appear vibrant and are not diluted by other colors, such as gray or white.
- Low Color: Colors appear closer to gray, more "muted" or "dull", and as they are blended other colors are reduced in intensity.
Color is like the flavor of the fruit. The high chroma is like a freshly squeezed, juicy orange with a strong flavor;
The low coloration is like willow juice with a lot of water added, and the flavor is muted.
● The principle of color mixing:
The color intensity (vividness) of a color decreases with the number of times it is mixed, for example, if yellow and red are blended to produce an orange, the blended orange will be less colorful than the orange extruded from a strip of pigment.
Gradient strips help us to understand how the intensity of a color affects the chromatic variation.
What is color brightness?
Brightness refers to how bright a color is, i.e. how light or dark it is.
- High brightness: The color is close to white, and looks brighter compared to colors with high luminosity.
- Low Brightness: The color is close to black and looks darker compared to a color with a high degree of brightness.
Brightness is like the intensity of a light. High brightness is like a room where the sun shines; low brightness is like a dimly lit corner.
Color brightness can be divided into high, medium, and low brightness from top to bottom by referring to the middle block of the diagram.
● Color brightness distribution
Brightness is an important element in painting to express light and shadow, space, and sense of three-dimensionality. We can briefly divide brightness into three types, light, gray, and dark brightness levels.
● Practical Examples
The green cube at the bottom of the picture.
In the light source from the right, simply divide the head into light side, shadow dark side, light side can be cadmium yellow, lemon yellow, blending the sky blue, the process must maintain the brightness of the color.
Shaded areas are not directly illuminated by light, and the green luminance needs to be separated from the bright color luminance.
1. Front faucet
After understanding the light/dark logic of the above simplified square, the following is an example of a dinosaur head on the left:
The green of the bright side can be Grass Green (Hobin W277) or a diluted color, please refer to the Brightness Colors section.
Shaded areas of green can be used Prussian blue (greenish blue) to blend yellow, note that the proportion of blue can be a little more, brightness contrast, please refer to the medium brightness block color.
You can see that the lighted surface is bright and clear, while the shadows are toned with cadmium yellow and darker blue to open up the brightness between the blocks, and a sense of three-dimensionality is established.
2. Layered understanding of dragon's head brightness
The dragon's head is divided into upper and lower layers, let's start with the upper layer.
The light source is from above, and we have simplified the upper faucet into two shades, a light purple on the lighted side as shade 1, and a blue-violet on the side as shade 2.
The chin is the lower layer, so the base brightness will be darker than the upper layer, you can use a deeper blue-purple, with different areas of brightness differences, you can build up the sense of the dragon head.
● Final Conclusion
When we want to draw three-dimensionality.
- Pay attention to the location of the light source and the direction of the irradiation angle, which will affect the position of the light and darkness and the intensity of the light.
- The shape of the object itself affects how the color is applied, ex: round, square.
- Pay attention to the brightness of the blended color and place it on the corresponding brightness position.
Above is the introduction of color mixing, chroma and luminance, do you have difficulties in watercolor painting or color mixing?
If you want to learn to draw, but don't know how to start, or are interested in understanding what drawing is all about.
