ASBC Beer Color and Turbidity

Posted on June 7, 2016 by Ken Phillips

ASBC Color The ASBC Beer Color scale has a range of approximately 1 to 11 units, with the more yellow, pale worts at the low end of the scale and the redder color of dark worts, beers and caramels at the upper end of the scale. The industry reference method for ASBC Beer Color and […]

Carbon Blackness [My], Jetness [Mc], Undertone [dM] and Tint Strength [T]

Posted on June 2, 2015 by Ken Phillips

“Carbon black, also called charcoal black lamp black, pigment black, soot or black carbon, is a fine particle carbon pigment obtained as soot from the incomplete combustion of many different types of organic materials, such as natural gas, or oil. Carbon black is usually a fine, soft, black powder. It is very stable and unaffected […]

What is Y Transmission?

Posted on April 23, 2015 by Ken Phillips

In addition to representing green in the CIE X, Y, Z tristimulus color scale, the CIE Y is also the 1924 CIE Luminosity or Brightness function which quantifies the way people perceive the relative brightness of equal energy spectral hues. Humans perceive green colors as brighter or more luminous than blue or red. Ken PhillipsMr. […]

What is Hunter Whiteness Index?

Posted on April 23, 2015 by Ken Phillips

Hunter Whiteness Index [WIH] There are at least half a dozen whiteness indices in use today, and a similar number of legacy whiteness indices no longer in use. There are subtleties among them and it is important to know the forms of these whiteness metrics and conditions for which they are derived for. In general, […]

Do you have a source for Magnesium Carbonate powder as top-of-scale?

Posted on July 22, 2014 by Ken Phillips

For measuring the brightness of some materials, some dated industrial methods cite a Magnesium Carbonate block standard to be set to Y = 100% in reflectance. This is a very old top-of-scale standard and HunterLab does not recommend using it. Ken PhillipsMr. Philips has spent the last 30 years in product development and management, technical […]
