- Colorimetry is the analysis of chemical samples to collect information about their concentration.It involves passing light through a sample and measuring how much is absorbed by the solution, using equipment like a spectrophotometer to measure as precisely as possible. spectrophotometer may be used during colorimetry. The therm colorimetry may be used to describe the study of how people perceive color and distinguish between colors. Colorimetry can be used to help people with colorblindness.

color temperature Related Terms. Color temperature refers to a characterization of the spectral properties of a light source and is commonly used during the production phase in the film and photography industries. Low color temperature is the warmer, more yellow to red light while high color temperature is the colder, more blue light. Daylight, for example, has a lower color temperature near dawn and a higher one during the day. The standard unit of measurement for color temperature is Kelvin (K).

Color blindness Color blindness, or color vision deficiency, is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions.Color blindness affects a significant percentage of the population.There is no actual blindness but there is a deficiency of color vision.rotanopia, deuteranopia, protanomaly, and deuteranomaly are commonly inherited forms of red-green color blindness which affect a substantial portion of the human population. Those affected have difficulty with discriminating red and green hues due to the absence or mutation of the red or green retinal photoreceptors.

Pulse oximetry Pulse oximetry is particularly convenient for noninvasive continuous measurement of blood oxygen saturation. In contrast, blood gas levels must otherwise be determined in a laboratory on a drawn blood sample.

Pulse Oximetry Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs.

A-level Applied Science/Finding out about substances/Colorimetry Procedure[edit] 1  Use the colorimeter to measure the absorbance of the water sample and the standard solutions across a range of wavelengths. Choose a suitable wavelength for the rest of the experiments.  As a group, decide on how you will need to dilute the standard solutions.

Trigonometry All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Trigonometry (from Greek trigōnon, triangle and metron, measure) is a branch of mathematics that studies relationships involving lengths and angles of triangles.

color 1. the quality of an object or substance with respect to light reflected by it, usu. determined visually by measurement of hue, saturation, and brightness of the reflected light; saturation or chroma; hue. 2. the natural hue of the skin, esp. of the face; complexion. 3. a ruddy complexion, usu. indicating good health.

ANTHROPOMETRY Anthropometry is the science that defines physical measures of a person’s size, form, and functional capacities. Applied to occupational injury prevention, anthropometric measurements are used to study the interaction of workers with tasks, tools, machines, vehicles, and personal protective equipment — especially to determine the degree of protection against dangerous exposures, whether chronic or acute.

- It measures the spectral reflectance of an object at each wavelength on the visible spectrum continuum. Spectrophotometry provides high accuracy and is generally used in research and color formulation applications. Colorimeters are generally used in production and quality control applications.

COLORIMETRIC ANALYSIS A colorimeter or spectrophotometer can be used to measure any test substance that is itself colored or can be reacted to produce a color. In fact a simple definition of colorimetry is the measurement of color and a colorimetric method is any technique used to evaluate an unknown color in reference to known colors.

It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe.

- By Dr Ananya Mandal, MD. Color blindness is a term that is commonly used to refer to color vision deficiency, a condition where the ability to see colors clearly, is reduced. Actual color blindness, however, is a rare condition referring to an inability to see any color at all.

- Color is the appearance of objects or light sources; caused by the emitance, reflection, or transmittance of light.   Color is measured in wavelengths. A sighted person … can see many colors with light, because they are reflected into a sighted person's eyes. There are hundreds of different colors.DDITIVE colors are like colored lights. SUBTRACTIVE colors are like paint. For additive colors, you can make yellow from adding red and green light. Or yellow, being a spectral color, means that light of a pure certain wavelength, around 570nm, is itself yellow.

Hue, Value, Saturation Hue, Value, Saturation. What is color? In short, color is the visual byproduct of the spectrum of light as it is either transmitted through a transparent medium, or as it is absorbed and reflected off a surface. Color is the light wavelengths that the human eye receives and processes from a reflected source.

Tonometry Tonometry is a test to measure the pressure inside your eyes. The test is used to screen for glaucoma. There are many methods of testing for glaucoma. The most accurate method measures the force needed to flatten an area of the cornea. The surface of the eye is numbed with eye drops.

Color blindness Color blindness. Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Color blindness can make some educational activities difficult. Buying fruit, picking clothing, and reading traffic lights can be more challenging, for example. Problems, however, are generally minor and most people adapt. People with total color blindness, however, may also have decreased visual acuity and be uncomfortable in bright environments. The most common cause of color

Blindness Color blindness is the inability to perceive differences in various shades of colors, particularly green and red, that others can distinguish. It is most often inherited (genetic) and affects about 8% of males and under 1% of women. People who are color blind usually have normal vision otherwise and can function well visually. This is actually not true blindness. Night blindness is a difficulty in seeing under situations of decreased illumination.
