International Gold Yellow Code
The International Gold Yellow Code (IGYC) is a standardized system for identifying and describing the color of gold. It was developed by the International Color Association (ICA) in collaboration with the World Gold Council (WGC). The IGYC consists of a series of six-digit codes, where each digit represents a different aspect of the gold’s color.
The first digit indicates the gold’s purity, or karat. The scale ranges from 0 to 24, with 24 karat being pure gold and lower karats indicating a higher percentage of alloy metals.
The second digit indicates the gold’s hue, which is the dominant color component. The scale ranges from 1 to 5, with 1 being a strong yellow hue and 5 being a strong red hue.
The third digit indicates the gold’s saturation, or intensity of color. The scale ranges from 1 to 5, with 1 being a very pale color and 5 being a very dark color.
The fourth digit indicates the gold’s value, or lightness or darkness. The scale ranges from 1 to 5, with 1 being very dark and 5 being very light.
The fifth and sixth digits indicate the gold’s tone, which is the overall impression of the color. The scale ranges from 1 to 5, with 1 being a warm tone and 5 being a cool tone.
The IGYC is a valuable tool for jewelers, goldsmiths, and other professionals who need to accurately identify and describe the color of gold. It provides a common language for communication about gold color, ensuring consistency and accuracy in the industry.
Here are some examples of IGYC codes:
* 241111 – Pure gold with a strong yellow hue, very pale color, and warm tone
* 182332 – 18 karat gold with a strong yellow hue, medium intensity, medium lightness, and warm tone
* 144413 – 14 karat gold with a strong red hue, high intensity, medium lightness, and cool tone
The IGYC is a widely recognized and respected color standard for gold. It is used by jewelers, goldsmiths, manufacturers, and other professionals around the world.
