Green is created by combining blue and yellow pigments. Yellow paint reflects the majority of light at long wavelengths while absorbing light at short wavelengths. Because blue and yellow paint both reflect middle (green-appearing) wavelengths, the combination appears green when blue and yellow paint are combined together.
Similarly, red can be made by combining blue and orange pigment, or blue and red pigment. The color purple can be made by mixing blue and violet pigment. In all these cases, the mixture of colors produces a result with properties intermediate to those of its components.
When you mix blue and yellow paints, they don't always make green; it depends on how they're mixed. If the mixture is very dark, there will be little reflection from longer wavelengths, so the result will appear gray rather than green. However, if the mixture is very pale, then more reflection at shorter wavelengths will occur, resulting in a color between blue and yellow/gray.
The same thing happens with blue and orange or blue and red pigment: The mixture may look either like blue or like orange/red depending on how it's done. There are many ways to combine colors, and each method has a different effect on the final color.
Finally, violet pigment does not exist as a pure color. Rather, it makes purple because it mixes with blue pigment to give a medium that falls in between blue and red on the color wheel.
In the case of "blue" paint, predominantly "red" light is absorbed, but in the case of "yellow" paint, largely "blue" light is absorbed, leaving green as the dominating remaining color. Green is the opposite of blue.
This is because the molecules that make up white oil paint (or any other kind of paint) stick together with some solvents and additives, causing their surfaces to be flat instead of spherical. Flat surfaces reflect light differently than spheres, which is why you can see through a canvas picture frame.
When light hits the surface of a yellow paint chip, it is mostly reflected back out into space, with only a little absorbed. This means that there are few brown or black spots where yellow paint meets the wall, as most of the light bounces off the surface. The same thing happens with red paint: most of the light is reflected, so there are few places where you can see it darkly stained on a wall. Blue paint looks green because most of the light is absorbed, so there are more places where it can stain the wall blue.
As you can see, the color of your painting will vary depending on what type of material it is made from. If you use white oil paint on a black wall, for example, the result will be white paint that looks black.
Because paint combines subtractively, Yellow+Cyan produces a good green. However, a dark blue paint absorbs some green light (but not all of it), resulting in a relatively dark green since the blue paint absorbs some green light. Similarly, what painters label "red" is actually more of a magenta... but that's another story.
Blue is a dominant hue. Green is a secondary hue formed by the combination of blue and yellow. In this case, you could theoretically apply so much blue paint to your green paint that it finally overwhelms any yellow in the green and is virtually blue. However, this would be difficult because most blue paints are actually mixtures of blue and white or black. So, even if you mixed enough blue paint together, it wouldn't be true blue.
The word "green" comes from the name of the ancient Greek god of healing, Asclepius. He was known as the "God of Medicine" because he cured people of diseases. His color was blue with white spots where patients had healed.
In English, "blue" is a more general term that includes both azure (a light sky-blue) and navy (a dark sea-blue). In French, they are called bleu and bleu, respectively. The word "green" also has multiple meanings in many languages around the world. It can mean "malachite" or "jade" in Latin, Farsi, Hebrew, Arabic, Sanskrit, and Turkish. It can also mean "grass" or "tree" in German and Finnish. Finally, "green" can mean "unmarried" in Welsh.
In conclusion, yes, there is a difference between green and blue.
Because our cones can only detect red, green, or blue light, they are the main hues of light. So, when we talk about light, red and green combine to make yellow, the secondary hue that exists midway between them. Colors in pigment (such as paint) are subtractive, making things more difficult. Everything except loading is absorbed by red pigment... so colors mix with everything else to form white, which isn't really a color itself but rather the absence of color.
Red, green, and yellow lights combined make white light. This is because red, green, and blue lenses will all pass some of the red, green, and blue light, respectively. However, since these lenses are not perfect, some of the other colors will also be transmitted along with it. For example, if you had a red lens, a green lens, and a blue lens, then you would get a mixture of red, green, and blue light being transmitted through those lenses. The more of each color there is, the brighter the lamp will be.
Lamps come in many different shapes and sizes; however, they all use the same principles at their heart – electricity flowing into one end of the lamp, out the other end. A lamp's color depends on how it is constructed. Most lamps are made from glass or plastic, which either absorb or reflect light based on what color they are coated with. Some include filaments, while others don't.
