No, the colors you see on your computer or mobile device screen serve only as an approximate representation of the final result; a 100% match cannot be guaranteed. This difference is mainly due to three factors:
Screen calibration: Monitors, tablets, and mobile phones emit light and display images in a digital color system (RGB). Brightness, contrast, and calibration vary greatly from device to device, which alters color perception.
Nature of the material: Unlike printing on white paper, coloring is applied to natural wood (birch or pine). The base color of the wood itself, its porosity, and the arrangement of the grain physically interact with the coloring process, creating nuances and tones that a digital screen cannot accurately simulate.
Combination of personalizations: If you choose to apply UV Printing or Laser Engraving over the colored wood, the final result of these applications might also not match the exact color you see in the simulator. The combination of the inks with the base color of the wood (or the reaction of the laser burn in the different grains) creates mixtures and physical effects that can deviate from the digital file's simulation. For these reasons, slight tonal variations between the digital simulation and the physical product received are perfectly normal and are not considered a production defect.
