What Transition Created the Color Red Chemistry?
The transition that creates the color red in chemistry is due to the absorption of light by molecules. This is a process known as light absorption.
When light particles, or photons, interact with molecules, an electron can become excited and jump to a higher energy state. When the electron jumps back down to its original energy state, it emits light.
If that emitted light is not the same color as the original light, then the molecule absorbs and reflects light of the complementary color. In the case of red, the photon is absorbed and blue light is reflected.

The Chemistry Behind the Creation of the Color Red
Red is one of the most eye-catching and vibrant colors that can be found in nature and in art. While it may appear to be a single color, the creation of the color red is actually a complex process that involves several different chemical reactions.
The following is a breakdown of the chemistry behind the creation of the color red:
1.Mixing Primary Colors: The primary colors red, blue, and yellow can be mixed together to create the color red. This method is used in the creation of paints and other art media.
2.The Use of Pigments: Pigments are used to create a range of hues and shades of red. Pigments are typically made up of organic compounds that absorb specific wavelengths of light, creating a range of colors.
3.Chemical Reactions: Chemical reactions can be used to create a wide variety of shades of red. For example, when ammonia and hydrogen peroxide are mixed, a bright red color is created.
4.Combining Elements: Different elements can be combined to create a wide range of red hues. For example, when iron and oxygen are mixed, the resulting compound is a red-brown hue.
The chemistry behind the creation of the color red is an intriguing and complex process. By understanding the basics of the chemical reactions involved, it is possible to create a wide range of shades and hues of red.
Introduction to Light Absorption and the Creation of Color
Light absorption is a process through which light energy is taken in by matter. This energy is then converted into other forms of energy, such as heat or chemical energy. Light absorption is essential for life on Earth and is responsible for the creation of color.
Light absorption occurs when photons (particles of light energy) interact with matter. The matter may be gas, liquid, or solid. Depending on the type of matter, the photons will be absorbed or reflected. The absorbed photons transfer their energy to the matter and generate heat.
When the matter is a solid, such as a pigment, the absorbed photons cause electrons to move to a higher energy state. This causes the pigment to emit a certain color in the visible spectrum.
This color is the result of the pigments absorbing light of certain wavelengths, while reflecting all other wavelengths back to our eyes.
For example, a pigment that absorbs blue light and reflects red, yellow and green light will appear to be red. Without the absorption of light, we would not be able to see a variety of colors that exist in the world.
What Happens When Photons Interact With Molecules?
When photons interact with molecules, they can cause various changes in the molecules. The interaction between photons and molecules depends on the type of molecule and the type of photon.
Generally speaking, when photons interact with molecules they can be:
Absorbed:
This is when the photon energy is transferred to the molecule, usually in the form of excitation energy. This is a common type of interaction and is often seen in photosynthesis and other natural processes.
Reflected:
This is when the photon bounces off the molecule, resulting in a change in the direction of the photon’s travel. This is often seen when light reflects off of a surface or object.
Transmitted:
This is when the photon moves through the molecule, resulting in a decrease in the intensity of the photon. This is common in materials like glass or plastic, which are transparent to certain wavelengths of light.
Scattered:
This is when the photon is redirected by the molecule, resulting in a change in the direction and intensity of the photon’s travel. This is common in the atmosphere, where sunlight is scattered by molecules in the air.
The way photons interact with molecules can result in a variety of phenomena, such as fluorescence, bioluminescence, and absorption spectroscopy.
Through the use of these methods, scientists are able to gain valuable insights into the structure and function of molecules in a variety of contexts.

The Electrons Jumping to a Higher Energy State
In physics, the concept of electrons jumping to a higher energy state refers to the process of electrons transitioning between energy levels.
This process, often referred to as ‘jumping’, occurs when an electron absorbs energy from its environment, usually in the form of a photon.
The energy absorbed causes the electron to jump from its lower energy state to a higher energy state.The transition of electrons from one energy level to another is an important part of many physical processes.
For example, in an atom, when electrons jump between energy states, they emit or absorb light. This phenomenon is known as fluorescence, which is responsible for the colors of many dyes, paints, and pigments.
In addition, the transition of electrons from one energy state to another is responsible for many of the electrical effects that power our everyday lives.
In summary, electrons jumping to a higher energy state is the process of electrons transitioning between energy levels.
This process occurs when an electron absorbs energy from its environment and is responsible for many aspects of our physical world, such as fluorescence and electrical effects.
When the Electron Jumps Back Down to its Original State
When an electron jumps back down to its original state, it is known as a “relaxation event”.
This event occurs when an electron absorbs energy from its environment, such as light or heat, and then releases the energy by transitioning to a lower energy state. This energy is then released as a photon, which is a form of electromagnetic radiation.
For example, if an electron on an atom is excited by heat, it may absorb some of the energy, causing it to jump to a higher level.
When the electron returns to its original state, it releases the energy as a photon, releasing the excess energy in the process. This phenomenon is an example of a relaxation event.
The Color That Is Emitted and Reflected
When light strikes an object, it can either be absorbed, reflected, or both. The color that is emitted and reflected is determined by the properties of the object.
When light is absorbed, the object will absorb some of the wavelengths of the light and reflect the other wavelengths. The color that is emitted and reflected is determined by the wavelengths that are not absorbed.
For example, a red object will absorb all the wavelengths of light except for red, so the color that is emitted and reflected from that object is red.
Similarly, when light is reflected, the object will reflect the wavelengths of light that it is composed of.
For example, a blue object will reflect blue light, so the color that is emitted and reflected from that object is blue.
In summary, the colors that are emitted and reflected depend on the properties of the object. If the object absorbs certain wavelengths of light, the colors that are emitted and reflected will be the colors that are not absorbed.
On the other hand, if the object reflects certain wavelengths of light, the colors that are emitted and reflected will be the colors that the object is composed of.
Why Is Red Reflected and Blue Absorbed?
When sunlight or other forms of visible light hit an object, the light’s energy is either absorbed, reflected or refracted. The colors that are reflected or absorbed are determined by the wavelength of the light that is hitting the object.
Red is reflected because it has a long wavelength, and blue has a short wavelength and is absorbed.
For example, if light of a certain wavelength hits a piece of red paper, the paper absorbs all the other wavelengths of light except the red one.
This is because the molecules in the paper are able to absorb the energy from the blue and green light, but the red light is reflected off the paper because its wavelength is too long for the molecules to absorb.
The same phenomenon happens with blue light, except that its wavelength is too short for the molecules to reflect, so the blue light is absorbed instead.
Summarizing the Chemistry Behind the Creation of Red Color
A red color is a result of a pigment, typically derived from organic compounds. When a light source is present, molecules that are exposed to light absorb certain wavelengths of visible light, reflecting the remaining wavelengths back to the viewer.
The wavelengths of light that are reflected back to the viewer give the color that is seen. In order to form a red pigment, the molecules must be able to absorb primarily the longer wavelengths of the visible light spectrum.
This is the basis behind the chemistry of creating a red color. In essence, molecules have to have a specific type of structure in order to reflect back longer wavelengths to the viewer and create a red color.
To illustrate this concept another way, consider a molecule of anthocyanin, which is found in many red fruits and flowers.
Anthocyanin has an extended polyene conjugated system that absorbs the shorter wavelengths of the visible light spectrum and reflects the longer wavelengths, resulting in a red color.
Therefore, the underlying chemistry of creating a red color is based on the fact that certain molecules can absorb certain wavelengths of light and reflect the remaining wavelengths back to the viewer to create a certain color.
