Abstract
Recent research has shown how to change the color of existing objects using photochromic materials. These materials can switch their appearance from transparent to colored when exposed to light of a certain wavelength. The color remains active even when the object is removed from the light source. The process is fully reversible allowing users to recolor the object as many times as they want. So far, these systems were limited to single color changes (i.e. transparent to colored). We present ColorMod, a method to accomplish multi-color changes (e.g., red-to-yellow). We achieve this using a multi-color pattern with one color per voxel across the surface of the object. When recoloring the object, our system locally activates only those voxels that have the desired color and turns all other voxels off. We describe Color Mod ’s hardware/software system and its user interface. The user interface comes with a conversion tool for 3D printing and a painting tool for matching physical voxels with the desired appearance. We also provide our own material formula for a 3D-printable photochromic ink.
