The Magic of Color-Matching Paint 3

We’ve all been there. You get a new sofa for the living room. Or a new bedspread for the bedroom. Suddenly you realize that the wall color is all wrong. The color you’ve lived with for the past fifteen years looks old and worn out, or is just a little bit off-shade to the new items you bought to match them (from your memory of the color).

Just about every paint company out there utilizes a paint color-matching system in their retail outlets. The system measures the color using a spectrophotometer, uses special software to calculate the colorants (and amount of each) required to match that color, and dispenses the colorant into a can of white or un-tinted paint base. A few minutes on the shaker and for under $100 the room can be made to match or coordinate with the new furniture or fabric.

Calibration and preventative maintenance have costs associated with them. And in uncertain economic times, these procedures can often become neglected or the interval between calibration and preventative maintenance can be extended in order to cut costs. However, neglecting calibration and preventive maintance can lead to the following: More…

Opacity is an important property of architectural paint. One coat hiding reduces labor costs of a paint job and is a competitive edge in promoting paints to professionals.

In the color and appearance measurement industry we like to use the phrase “correlate to the visual” when describing measurements. This means that instruments that measure appearance properties should give data that supports what we see with our eyes. More…

When it comes time to buy a spectrophotometer it’s important to buy the right spectrophotometer. Nothing will make you feel worse than buying an instrument and then finding out that it doesn’t meet your customers’ requirements, or doesn’t provide you all of the information you need internally. In many cases you will not have a choice; your customer or supplier, or an ASTM or ISO specification will tell you what you need to buy.

Whiteness Explained 1

While rarely found in nature, white is the color encountered most often in the human environment. It is the color of neutrality, of cleanliness and freshness. White provides contrast with other colors, and can increase the visibility of a logo or printed text. Conversely, yellow is the color of age, of things that are old and worn and uncared for. That’s why for product manufacturers that make white materials or use white packaging, it’s important to get a consistent color with high whiteness to convey to their customers that sense of freshness, that the product is new and clean.

A well-known, if extremely rough, convention in the world of color measurement says that in CIEL*a*b* or CIEL*C*h space, a dE* value of less than one indicates that two colors are visually indistinguishable to the human eye. The reality is far more complex than this. The limits of visual perception actually differ depending upon which portion of color space is being discussed.

Color instruments and software packages all contain references to CIE standard illuminants and observers. What do these terms mean and how are they used in practical color evaluations? The CIE (from the French Commission Internationale de L’Eclairage), or International Commission on Illumination, is the worldwide authority on how we see and measure color. BYK-Gardner uses many of these standards in its instruments and available software packages. This paper will give some easy to understand explanations of these standards and how they should be used.
