Spectro 1 Device FAQs

If a match is less than 1 dE, a touch up project can be considered. Extreme care must be taken with sheen selection and color production during mixing.

Spectro 1 will blend a multi-colored measurement surface within the 8mm diameter measurement area.

Custom colors can be saved and using Variable Cloud the saved colors can be packaged into new custom color libraries.

Please contact our Sales department.

While Spectro 1 and Color Muse are both reliable forms of color measurement, they each address different needs in accuracy, tolerance, and scenarios. Please refer to our blog post to help determine which device is right for you.

Unless the Spectro 1 is damaged, it is very unusual to see a degradation of performance. To verify accuracy of Spectro 1, the user can check against know color swatches from brands listed in our app.

Once the Spectro 1 device has been received, the user can scan and save color standards then periodically check against the color standards. Please keep in mind that physical color standards may drift over time.

Spectro 1 differs from normal spectrophotometers in price, portability, and software. At $300, Spectro 1 costs only a fraction of the price of standard spectros with bluetooth capabilities that allow for untethered color communication between instrument and database.

Base version of the Spectro app is FREE. More advanced features and color libraries are offered under our subscription plans.

Illuminants refer to the type of light used to calculate the best match during a scan. Each illuminant stands for the following: D50 (Sunrise or Sunset), D65 (Noon Daylight), F2 (Fluorescent Office Light), F7 (Fluorescent Daylight), A (Incandescent Light). You should select the illuminant closest to the light the surface you are painting will be in. The app has defaulted to D50, the most common illuminant used.

General Color FAQs

This can be accomplished if a user has Adobe Photoshop. To achieve this you would need to open up the Photoshop Color Picker, plug in the d50 Lab color into the picker, then click on the Color Libraries button to see the closest Pantone (or other library) color in Photoshop. This will pull up the closest Pantone color in the “Photoshop color space”.

Web colors are colors used in displaying web pages, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a hex triplet) or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.

CMYK is a scheme for combining primary pigments. The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself.

At this time we do not support CMYK due to the large number/variations of standards available.

Delta E is a unit of measurement for color difference perceived by humans. The E stands for Empfindung; German for “sensation”. The scale goes from 0 to 100 with 0 meaning no color difference and 100 being the greatest color difference possible. Delta E has evolved quite a bit over the last four decades. It started as a simple mathematical calculation to later a calculation that incorporates adjustments to account for variations in a human’s ability to perceive color differences in different color regions. In the most modern delta E standards (delta E CMC, 2000), a delta E of less than 1.0 is not perceivable by most humans. People who either have superior color vision or have received specific training can perceive color differences down to 0.6 delta E.

Lab color space describes mathematically all perceivable colors in the three dimensions. L for lightness and a and b for the color opponents green–red and blue–yellow.

LCH is a type of Lab color space.

Both are types of illuminants constructed to represent natural daylight. The primary difference between the two is the color temperature of the light they are meant to represent.
