The ability continues to grow stronger over time. The perceptions are generally not overwhelming or distractive. I enjoy learning about the fascinating things I see. The information perceived through this ability is not superimposed over my vision of the world through eyesight but is perceived only in my mind. I can by choice try to overlap my normal vision with this special vision to better search out health information.

When I encounter something that comes with a definite identity, such as pure calcium in a container, I learn to identify its feeling with its name and from then on when I come across the same feeling I connect it to its name. This way I build a growing library of words and names that help me describe to others what I am seeing.

The medical health perceptions are often very specific and detailed, and often I can not confirm them by what I see when I look at the person with my ordinary eyesight and I have doubt in what I've perceived, but still, so far, I have not had a single verified incorrect perception! Most of the time my ability works on its own without any effort from me, just like when you see a page with written text you read the words whether you choose to or not and it is hard not to read it since it's there. I can also choose to search for information. See this page on Observations made with my ability, where I now write down the specific things that I see with my ability and keep a score on correct, incorrect, and undetermined accuracy of observations.

Chemical Color-Synesthesia
On the small scale of atoms and chemicals, I perceive things in interesting colors that are not the same as the colors we see when we look at chemicals with our eyes. It bothers me that chemistry molecule sets that are used to attach different colored atoms together to make three-dimensional physical models of molecules are in different colors than what I see. In my vision, nitrogen is neon green, phosphorus deep blue, potassium light blue, hydrogen red. Carbon is black, argon is a kind of purple-red, calcium a light blue (different shade of light blue than potassium). I have like an internal spectroscope in my mind that distinguishes atoms around me by their color and feeling. I have not confirmed whether this occurs only when I have prior knowledge about the chemical (which would make it nothing more than synesthesia) or whether I would be accessing information that is not accessible to ordinary senses of perception (which would be extrasensory perception). I have had some interesting experiences with this as well.

Hydrogen: H

I still do not perceive a color associated to every chemical element. To me, chlorine is a deep turquoise, and sodium is metallic gray yellow. I only need to see the abbreviated letter(s) of a chemical element in order for it to trigger the perception of the color. It is always the same color for the same chemical element. I am curious about perceiving sodium as yellow, since the actual color of its flame happens to be yellow, as in here and here. Sodium itself is a grey (alkali) metal but is rarely found in its pure metal form since it is highly reactive and occurs as the positively charged sodium ion in combinations with other negatively charged ions as ionic compounds, one of the more well-known being sodium chloride, table salt. In its ionic form the ionic compound tends to have white color, depending on the negative species. So there appears to be nothing yellow about sodium itself. But to me, when I look at or think of chemical elements, each has its distinct color that is not the same as the color we see with our eyes.

Each chemical element (a distinctly different type of atom) is unique and they can be distinguished or identified in science by using spectroscopic techniques. Electromagnetic radiation occurs to a wide range of frequencies, that is, how fast it is vibrating. Different frequencies make radiation very different and that is when we have its many expressions such as X-rays, ultraviolet radiation, visible light (colors), infrared (heat!), microwaves, all of which are electromagnetic radiation but only differ in frequency. What makes the chemical elements different from one another is the size of their nucleus, which enables a corresponding amount of electrons around it as well as electron distribution depending on the extent of the nucleus. In this way, each different chemical element such as carbon, sulfur, phosphorus or nitrogen although made of the same material, become different from one another. It is considered that it is this difference in electron distribution that is what essentially makes the elements distinguish from one another in their behavior and properties since it is at the electrons, not the nucleus, that most of the chemical properties take place. In fact, one can construct something called quantum dots in which it is possible to construct "atoms" without the nuclei just by use of artificially obtained electron distribution to mimic chemical elements and to obtain their reactivity and behavior.

When atoms are exposed to electromagnetic radiation, they absorb some of the radiation (photons) whose frequencies match what that particular atom or ion can absorb, different for each species. These absorbed photons are collected in the atom and later re-emitted. When a detection instrument is used to record the photons that were absorbed and then re-emitted by the atoms in a chemical sample it produces a unique and distinct emission spectrum that displays on a graph what frequencies of light were absorbed/re-emitted by the chemical sample. For pure samples (that are not mixtures) these emission spectra produce "fingerprints" that help to identify what atoms were in the sample.
Here is the emission spectra that is specific to sodium: yellow sodium emission spectra. Not only is the visible flame of sodium yellow, so is its emission spectra.
Some of the other emission spectra of chemical elements are somewhat reminiscent with my perception of them also. It might be a coincidence, or due to something else. Here is hydrogen - it is red!
I perceive nitrogen as green. Its emission spectra has quite a bit of blue-green in it, but also red that I do not perceive.
I perceive oxygen as colorless, perhaps because most of its emission lines are on a high frequency that would be difficult to translate into color? (Because the human eye perceives visible color only up to a certain high frequency.)
Silicon I perceive as a grey-blue, which is consistent with its emission spectra again if you disregard the red lines.
To me sulfur is yellow-orange.
To me argon is purple-red or brown-red, and its emission spectra is with the exception of one strong line, definitely not that.
The potassium emission spectra is very consistent with the light-blue that I see.
To me calcium is a blue and again I do not perceive the red in it at all.
The emission spectra of some chemical elements seem consistent with the color I perceive with them, whereas for others there seems to be no correlation.
