Measurement results

NANO is the most accurate device on the market on textured surfaces.

Here below the L*a*b* values measured on a green sample by an independent laboratory.
The sample consists of 3 areas painted with the same green color. The first area, plain flat, measured with a spectrophotometer N°1 is used as reference value (marked with bold font face in the here below list). The second area, has a textile texture and the third area has a wall structure of 2 mm. NANO is the most accurate device, it has the smallest delta E on textile and textured surfaces. NANO reads and measures 50'000 pixels separately. During this reading process it automatically eliminates all non-dominant colors such as shade effects and dirty surfaces. This can not be done with other devices because they make an average with all the measurement area.


We have so far developed more than 40 iOS and Android apps for paint manufacturers around the world.

Our applications are compatible with our COLORCATCH NANO. By connecting the device to our applications you can in one click measure / search the closest color of a selected color card. It is also possible to measure the exact values L*a*b*, sRGB, and CMYK. In one click, the color you measure with the NANO will be applied to the wall of the house you pre-painted. Your customers will never forget this magic moment.

By clicking on the App Store or Google Play Store icons below you will immediately access the list of these applications. Please note that not all applications developed are necessarily active in your country.
