Sto-Colorix Colour and architecture are intrinsically linked. For this reason, the Sto App now also provides you with an electronic access to the entire StoColor System. The Sto-Colorix App contains the well-known Colorix software as well as all colour shades of the StoColor System. The App is compatible with Apple's iPhone, iPad and iPod systems. The colours of pictures of i.e. buildings, walls, etc. that were taken with an iPhone or iPad can be changed within seconds. A conventional colour chart is, therefore, no longer necessary. The pictures redesigned using the Sto-Colorix App, along with information on the applied colour shades, can be digitally stored and then instantly forwarded via e-mail. The StoColor System Sto's classic is the StoColor System. The human visual perception forms the basis of this system. This direct link to the emotive aspect of colour is the key to the StoColor System and its intuitive use. The Sto-Colorix App is particularly user-friendly. It allows for the colour shades available in the StoColor System to be applied directly onto an object and to be subsequently sent off electronically. AC-Architectural Colours presents durable and material-oriented colours especially for building envelopes. All 300 colour shades can be delivered as silicone resin or Lotusan paints. Most of them are also suitable for coating organic and mineral external wall insulation systems. Professional colour measurements of smooth and textured surfaces can be effortlessly done with the COLORCATCH NANO system. This device incorporates a revolutionary new technology (patent pending) to accurately measure the color of smooth, structured or patterned surfaces to determine the corresponding color of the preselected swatch. NANO reads and measures 50'000 pixels separately. During reading it eliminates automatically all non-dominant colors such as shade effects and dirty surfaces. It's the ideal equipment for any tradesman in order to measure paint bases, to apply the measured values directly to a picture and to immediately send it off electronically. Sto-Colorix App and COLORCATCH NANO colour measurement systems mean: "THE STATE OF THE ART IN DIGITAL COLOUR COMMUNICATION" Due to technical limitations, colors seen in this App may not accurately reflect paint colors. To confirm your color choices refer to your color cards.
