Technical Reports on Color

skip to main navigation

Given that some of the products Sensus produces are tea, coffee, and hibiscus, color is a necessary concern. Not only measuring color, but enhancing and preserving color is common research topics.

Multiple methods to measure color are used at Sensus. First is a visual comparison to standards. Secondly is to measure the tinctorial power and hue using a UV-VIS spectrometer. These methods are used by in the caramel color industry for measuring brown tones. Additionally, a colorimeter is used to measure the LAB values for the LAB color space. Below is a graphical representation of the LAB color sphere.
