Packaging: Contrast of color elements with its color system

1. Color color and color system The three-dimensional color system is based on the relationship between hue, lightness, and purity of colors. With the help of three-dimensional space, a three-dimensional model similar to a sphere is formed by using the method of rotating right-angled coordinates. Its structure has been compared to the shape of the globe. The north pole is white, the south pole is black, the axis connecting the north and south poles through the center is the lightness axis, the northern hemisphere is the light color system, and the northern and southern hemispheres are dark colors. The position of the hue circle is on the equator line, and the point of gravity is a heavy straight line from the center axis to the purity standard. The closer to the center, the lower the purity, and the center of the ball is a positive gray.
There are many kinds of three-dimensional color, mainly in the United States, the color of the three-dimensional color, Germany Ostwald color three-dimensional, Japan color research three-dimensional and so on.
Monselle color system 2, the three elements of color and the basic type of color contrast color more than two color combinations, the color contrast effect due to the formation of the color contrast effect is called color relative ratio. It is a fundamental aspect of color contrast. The degree of contrast depends on the distance (angle) between the hue rings on the hue circle. The smaller the distance (angle), the stronger the contrast, and vice versa.
Zero Degree Comparison (1) Achromatic Color Comparison Achromatic Color Comparison Although there is no hue, their combination is very valuable in practical use. Such as black and white, black and gray, medium gray and light gray, or black and white and gray, black and dark gray and light gray and so on. The contrast effect feels generous, solemn, elegant and modern, but it also tends to produce a monotonous sense of monotony.
(2) Achromatic and chromatic pairs such as black and red, gray and purple, or black and white and yellow, white and gray and blue. The contrast effect feels generous and lively. When the area without color is large, it tends to be elegant and dignified. When there is a large area, the liveliness is strengthened.
(3) The contrast of the same kind of color to the different brightness or different purity of one kind of hue, commonly called the sister color combination. Such as blue and light blue (blue + white) color contrast, orange and coffee (orange + gray) or green and pink green (green + white) and dark green (green + black) color contrast. The contrast effect feels unified, quiet, elegant, subtle, and stable, but it is also prone to monotonous and dull problems.
(4) Compared with the same color, achromatic colors such as white and dark blue and light blue, black and orange and brown are compared, and the effect combines the advantages of types (2) and (3). Feeling both a certain level and generous, lively and stable.
3, harmonic contrast (1) adjacent color relative to the adjacent two-three color contrast on the hue ring, hue distance of about 30 degrees, for the weak contrast type. Such as red orange and orange and yellow orange contrast. The effect feels soft, harmonious, elegant and quiet, but it also feels monotonous, ambiguous, boring, and powerless, and the brightness difference must be adjusted to enhance the effect.
(2) Relative color contrast ratio of similar color is about 60 degrees, which is a weaker contrast type, such as the contrast between red and yellow orange. The effect is more plentiful and lively, but it still has the feeling of unity, elegance and harmony.
(3) The relative color contrast ratio is approximately 90 degrees relative to the distance. It is a type of medium contrast, such as the contrast between yellow and green. The effect is bright, lively, full, exciting, and interesting. The contrast has considerable strength. Does not miss the sense of harmony.
4. Strong contrast (1) Relative color contrast ratio Relative color distance is about 120 degrees, which is a strong contrast type, such as the contrast between yellow-green and red-purple. The effect is strong, eye-catching, powerful, lively, and rich, but it is not easy to unify and feel cluttered, stimulating, and causing visual fatigue. Generally need to use a variety of blending means to improve the contrast effect.
(2) Complementary color The contrast ratio is 180 degrees, which is an extreme contrast type, such as red and blue-green, yellow and blue-purple contrast. The effect is strong, dazzling, loud, and extremely powerful. However, if handled improperly, it can easily produce naive, primitive, vulgar, unsteady, and uncoordinated bad feelings.
