What Two Colors Make Yellow:
Two colors make yellow when they are combined. For example, if you mix red and green paint, you get yellow.
Industrious people have invented many ways to produce yellow without mixing paints or raw materials, saving less time than their painting counterparts.
How to create artificial yellow:
There are two main ways of obtaining yellow in the lab: light and electricity. If you shine a high-intensity light onto a substance, some of the light particles may hit an electron and cause it to leave its atom.
Since electrons orbit their atoms like planets around the sun, this causes the bit to become positively charged (also known as an ion). The color of light that causes this effect depends on the element type and how much energy the original photon gave off; for instance, neon atoms emit red or violet photons when ionized, while sodium releases a bright yellow light photon.
These excited atoms may release photons themselves to return to their ground state, meaning that the light emitting from a material may be composed of several colors.
The second way of obtaining yellow is through electricity. This technique uses an electric current to strip electrons away from atoms, and like the light method, the color of the emission depends on what type of atom is being ionized.
For example, if you use a gas discharge tube containing mercury vapor, you will see a strong yellow light emitted from the line. These methods have been used in research and industry for many years to create compounds that would otherwise be difficult or impossible to synthesize.
One such application is in fluorescent dyes- by adding a small amount of a dye that fluoresces under UV light to another material, it is possible to see where the paint has been deposited. This is often used in forensics to detect blood or other biological materials at crime scenes.
How to make yellow color with watercolor:
Watercolors are a type of paint that can be used to create beautiful works of art, but they can also be used for more practical purposes, such as coloring in drawings or making cards. To make yellow, you need two primary colors- red and green.
To mix them, start by putting a small amount of green paint onto your palette. Next, add a little red color to the green and mix them until you have a light green shade. Then, add more red until you have a brighter yellow; don’t add too much or become orange. Finally, add some water to the paint and mix it until it is the desired consistency.
How to make yellow without green:
yellow is a color you can make without using the primary colors green, blue or red. You need to mix equal parts of magnets and iron powders to make yellow.
The magnetic power will pull away some of the electrons from the iron atoms, leaving them positively charged. When these charged particles are exposed to oxygen, they form compounds known as oxides. Since oxygen has eight protons, it will pick up two electrons for everyone that leaves an atom- this causes it to become negatively charged instead of positive (or cationic).
When these charges meet each other on opposite ends of their attraction, collide into each other,r and then repel and again collide and repel multiple times,s they create an electric current.
This voltage is the same as that of a typical battery. Still, since this chemical reaction creates it without involving any positive or negative electrodes (required for batteries), it is called a voltaic cell.
These cells are dangerous to humans; if you touch both ends at once with your bare hands, you will feel an electric shock and could be severely injured or die depending on how strong the voltage was. For this reason, people who use these types of chemicals should always wear safety goggles and gloves when working with them.
The amount of time needed to charge up the cell depends on how much iron powder
you have about how much magnetite there is, but it is usually on the order of a few minutes. Once it is charged, it will continue to produce a voltage as long as oxygen is available.
The same chemical reaction will occur if you mix equal iron oxide and magnesium powder parts. Magnesium melts at a lower temperature than iron (660 °C), so it will begin to melt the moment it touches the other components. The oxygen will be released as a gas, creating an explosive mixture if there is enough of it.
If someone were to try to light this type of mixture on fire, it would explode with enough force to seriously injure them or kill them, depending on how close they are standing next to it. This is why people should take great care when working with chemicals like these.
