Color is one of the most important properties of a fabric, and also one of the most difficult to get consistency throughout processes. Even in the physical world, color represents a huge challenge for producers and designers. Having to correctly translate the physical color of a fabric, to its digital representation, is quite a challenge.
The problem comes when the device you are using to scan your material is just not able to capture the real color of the fabric. This happens with neon, metallic and sometimes white fabrics, whereas the device can’t capture the color as it is, the digital fabric appearance will be very different than the real one. These kinds of materials require more sophisticated texture maps and render engines that can show the true color of the fabric or even its metallic properties.
That is why, the best results will be achieved by fabrics, piece or yarn dyed, with matte colors. There will always be a perceptual difference in color between a physical fabric and its digital counterpart since the environment in which we see them is different. But, if the device we use to capture the material is able to translate the color to a screen, the resulting digital material will be a good representation for the original one. Before submitting your images for digitalization, make sure you are happy with how the image represents the color of your fabric.
