Yellow+blue = green
Red+blue = purple
Red+Green = Brown
Red+yellow+white = skin color
Magenta+Yellow+Blue = Black
Red+green+ultramarine = white
Blue is the primary color.
Question 2: What kinds of colors are mixed with blue? Blue is the primary color, not the hue. Harmony of basic colors:
Red plus yellow becomes orange, red plus blue becomes purple, and yellow plus blue becomes green. Red, yellow and blue are the three primary colors, and orange, purple and green are the three primary colors. Intermittent colors and intermediate colors will turn into various grays. But all grays should have a color tendency, such as blue gray, purple gray, yellow gray and so on.
1. Red plus yellow becomes orange -2. Less yellow and more red become dark orange, 3. Red is less yellow and more becomes pale yellow. Red plus blue becomes purple -5. Less blue and more red become purple, more red becomes rose, 6. Yellow plus blue becomes green -7. Less yellow, more blue, and dark blue. 8. Less blue and more yellow to light green 9. Red with yellow and less blue becomes brown-10. Red plus yellow plus blue becomes grayish black (various shades can be adjusted according to the weight)-. Add white 13 to khaki. Yellow plus less red to dark yellow 14. Yellow plus blue plus green plus white plus milky green 15. Red plus yellow plus less blue plus white to light brown. 6. Red plus yellow plus blue to gray black plus more white to light gray 17. Yellow plus blue to green and blue to blue and green 18. Intermittent colors and intermediate colors will turn into various grays.
Question 3: What color turns blue with what color? 20 minutes is one of the three primary colors. It is not a composite color, it is a single color.
Blue has the shortest wavelength among the three primary colors, ranging from 440 to 475 N nanometers, which belongs to short wavelength. Blue is a symbol of eternity. There are many kinds of blue, and each blue represents different politics or other meaning. There are also many examples of music, books and stars named in blue.
The complementary color of blue is yellow. The contrast color of blue is orange. The couple color of blue is pink, and the adjacent colors of blue are green, cyan and staring color.
Primary colors refer to "basic colors" that cannot be obtained by mixing other colors.
Other new colors can be mixed with different proportions of primary colors. If the mathematical vector space is used to explain the color system, then the primary colors can be used as a set of basis vectors in the space and can be combined into a "color space". The color space seen by naked eyes usually consists of three basic colors, which are called "three primary colors".
Question 4: What color is blue? Blue is one of the three primary colors and cannot be matched with other colors. Blue only appears when it can be combined with another color.
Question 5: What color is blue? Red+yellow = orange yellow+blue = green red+blue = purple red+green = brown red+yellow+white = skin magenta+yellow+blue = black red+green+ultramarine = white is originally three primary colors.
Question 6: What color is red, yellow and blue? Red, yellow and blue are the three primary colors, and all colors in nature can be combined by red, yellow and blue. Red plus yellow turns orange, yellow plus blue turns green, and blue plus red turns purple. Simply put: red, yellow and blue are the three primary colors that can dominate the city? Any color composition. I don't know if it's right. This is my understanding.
Question 7: What color is the earth? Seen from outer space
White, white clouds.
Brown, brown continents and islands.
Blue, blue ocean.
Or,
Seen from outer space, the earth is a blue planet, and 78% of its surface is covered by the ocean.
From a deep and structural point of view,
The earth can be regarded as a series of concentric layers. There are core, mantle and crust structures in the earth. Outside the earth, there are hydrosphere, atmosphere and magnetosphere, which form a coat around the solid earth. The magnetosphere and atmosphere block the direct bombardment of the ground by ultraviolet rays, X-rays, high-energy particles and countless meteors from space. More than seven tenths of the earth's surface is covered by blue ocean. Lakes and rivers account for only a small part of the earth's surface waters. The liquid water layer on the earth's surface, called hydrosphere, has been formed for at least 3 billion years. The surface of the earth is composed of all kinds of rocks and soils. The ground is rugged and low-lying areas are flooded into oceans and lakes. There are plains and mountains on the land above the water. The total vertical fluctuation of the earth's solid surface is about 20km, which is the height difference between the top of Mount Qomolangma (measured by the China mountaineering team, the elevation of Mount Qomolangma is 8844.43m) and the deepest part of the ocean (the depth of Mariana Trench is about 1 1 km), which is more than half of the average thickness of the continental crust. The seabed is as different as land. Not calm. The rocks on the seabed are much younger than those on land. Most rocks on land are less than 2 billion years old. Sedimentary rocks can be seen everywhere on the land, indicating that these places may be oceans in ancient times. Although there are a few craters on the surface, it is difficult to find as many craters as the moon, Mars and Mercury. This is because the earth's surface is affected by external forces (water and atmosphere) and internal forces (earthquakes and volcanoes). The result of continuous weathering, erosion and disintegration. For a long time, it has been thought that the crustal tectonic movement is mainly characterized by the uplift and subsidence of the ground, with vertical movement as the main movement and horizontal movement as the supplement. In recent ten years, more and more scientists believe that there is not only vertical movement but also greater horizontal movement in the upper part of the earth. During the geological period, the relative position of the ocean and the mainland is also changing. 19 12 years, Wei Gena put forward the continental drift hypothesis. Since then, some geologists believe that there are two ancient continents on the earth-Gondwana in the southern hemisphere and Lauya in the northern hemisphere. But for a long time, many scientists refused to admit the hypothesis of continental drift, because it was hard to believe that there was such a great force to tear apart the original continental block. In the early 1960s, Hess and Dietz put forward the hypothesis of submarine expansion, arguing that global tectonics is the direct result of continuous submarine expansion. It is precisely because of the development of the hypothesis of seafloor spreading and the theory of plate movement that the theory of continental drift has been paid attention to again. The top layer of the earth is the lithosphere with a thickness of tens of kilometers, and the lower layer is the asthenosphere with low intensity. Under long-term stress, the material of this layer is plastic. The lithosphere floats on the asthenosphere. When the energy (primary heat and radioactive heat) in the earth is released, the uneven distribution of temperature and density in the earth causes the convection movement of mantle materials. Convective matter in the mantle moves to both sides along the cracks in the mid-ocean ridge of the ocean floor, and constantly forms a new ocean floor. In addition, the ancient seabed continues to expand outward. When they are close to the continental margin, they are dragged down by mantle convection and inserted under the continental crust, causing a series of tectonic movements of the lithosphere. This convection can renew the whole seabed every 300 million years. The lithosphere is divided into several discontinuous units by some active tectonic zones. Rebichon, known as the continental plate, divides the global lithosphere into six plates: Eurasian plate, American plate, African plate, Pacific plate, Australian plate and Antarctic plate. The expansion of the seabed led to the movement of continental plates. The mutual compression of plates has created a huge mountain system, from the Alps through Turkey, the Caucasus to the Himalayas. In some places, the rocks of the two plates sank at the same time, which led to the abyss of the seabed. In addition, plate movement also caused volcanoes and earthquakes. The theory of plate motion is still developing, and there are many controversial issues.
