How to visually detect organic pigments

Visual inspection is also the main method of color and light testing of organic pigments. In the international measurement of pigment color light, whether in the test equipment, light source conditions, observation environment and the observer's own color conditions have been made more stringent provisions, the aim is to make parallel comparisons under the same conditions.

This kind of visual inspection method, such as strict, should also have a certain observation conditions and have a certain color knowledge observer, in normal circumstances with the naked eye observation although quite keen, but there are still certain limitations. For the observation of organic pigment color light, it is more difficult to save as a data, and can not reflect the difference of the three parameters of accurate color between the pigments.

Nevertheless, the visual method will retain its certain value, the use of the human eye's acumen, the perceived difference in color can make a final evaluation of instrument detection. It is best to combine modern pigment analysis means, the total color difference, and then combined with visual inspection to objectively evaluate the color so that our evaluation of organic pigment color more perfect.
