EP (European Pharmacopoeia) and USP (United States Pharmacopoeia) color standards are commonly used to evaluate liquid pharmaceuticals. Both EP and USP rely on visual assessment. This method has its limitation as it is prone to human error and is subjective. Konica Minolta Spectrophotometer CM-5, equipped with both EP and USP indices, allows users to achieve accurate and repeatable color measurement of pharmaceuticals with ease. It also offers other industrial standard color indices and major colorimetric systems like APHA/Hazen, Gardner, Iodine Color Number, L*a*b*, and and L*C*h.
For routine grading of liquid chemical products that are clear or slightly yellow tinted, APHA Color, also called Hazen or Platinum Cobalt (Pt-Co) scale, is commonly used. The APHA color is a single-number color scale ranging from 0 (achromatic clear) to 500 (light yellow). The APHA color scale relies on visual comparison against samples. This method is subjective and difficult to maintain consistent color judgment.
For liquid chemical products which are yellowish to reddish, color grading scales like the Gardner color scale is commonly used. The earliest form of this scale was made up of 18 standard liquid solutions, and the colored glass scale was introduced afterward to improve stability and accuracy.
Both the liquid and glass scales rely on comparing samples against the standards visually. Both methods are subjective and difficult to maintain consistent color judgment.
Color communicates freshness, flavor, and quality. Customer often evaluates foods based on their colors and associate these colors to certain tastes. It is, therefore, important to ensure the color is right and consistent through objective and repeatable measurement methods from raw materials and ingredients, down to the final product.

Color perception is subjected to individual interpretation and this makes color communication difficult and vague. To better understand precise color communication, we must first understand the three attributes of color; hue, lightness and saturation. By creating a scales for hue, lightness and saturation, we can then express color numerically.
Metamerism happens when the two objects with the same color appear identical under one light source but different under another light source.This phenomenon is mainly caused by the variations in pigments, dyestuff or materials.
An infinite number of colors surround us in our everyday lives.It influence our tastes in food and other purchases, and it can also tell us about that person’s health. Even though colors affect us so much, our knowledge of color and its control is often insufficient, leading to a variety of problems in deciding product color or in business transactions involving color.
