Color analysis can be conducted by-eye, usually matching specimen color with reference charts. This methodology has been used extensively in soil analysis, often using the Munsell color system as the reference. [1] [2] While this is a traditionally used method, it is considerably subjective, relying on the ability of the naked eye to match colors.
But City University test contains test plates that can be used to detect all types of color vision deficiencies. [4] The TCU test was derived from Farnsworth D15 color arrangement test. [2] The test consists of 10 plates, containing a central colored dot surrounded by four peripheral dots of different colors.
The equipment required is a colorimeter, some cuvettes and a suitable color reagent. The process may be automated, e.g. by the use of an AutoAnalyzer or by flow injection analysis. Recently, colorimetric analyses developed for colorimeters have been adapted for use with plate readers to speed up analysis and reduce the waste stream. [1]
Although it's a handy tool, there's still a lot of guessing involved when you try to do a color analysis on your own. After attempting to do it myself, I decided to consult an expert. What's up, guys.

The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

The color analysis filter is a great way to find your colors if you're on a budget — but know that it won't go into nearly as much detail as a professional like Dobkine would. What you should ...
Colorimetric assays use reagents that undergo a measurable color change in the presence of the analyte. They are widely used in biochemistry to test for the presence of enzymes, specific compounds, antibodies, hormones and many more analytes. For example, para-Nitrophenylphosphate is converted into a yellow product by alkaline phosphatase enzyme.
