Colorigins is a tactile color mixing and matching game designed and developed for the Sifteo Cubes tangible computing platform. By physically manipulating a set of Sifteo Cubes, players attempt to match a target color by mixing a provided set of source colors. Throughout the process of color mixing, players can gain experience with key color theory concepts such as value, saturation, tints, shades, tones, complements, chromatic neutrals, and the relative visual strengths of particular colors. A custom algorithm that references the spectral reflectance values of Colorigins’ source colors enables the game’s digital simulation of subtractive color mixture.
Hardware and interface
Colorigins is specifically designed and developed for the Sifteo Cubes tangible computing platform. The Sifteo base stores and runs software built for the platform, connecting wirelessly to up to twelve 1.7-inch square cubes. The cubes each feature a touch sensitive LCD, an accelerometer, and proximity sensors so that the cubes know when and where they are in contact with one another. Colorigins leverages the unique hardware features of the Sifteo Cubes to create a minimal, intuitive, and novel user interface, fusing the distinctively physical experience of mixing color with the affordances of digital media. Colorigins, like many other applications involving tangible interfaces, incorporates a form of human-computer interaction that contemporary design practice has yet to fully address. In part, Colorigins examines the implications that this evolving human-computer relationship has for designing interactive experiences.
Simulating subtractive color mixture
The physical variables of subtractive color (such as ink / pigment characteristics, surface quality, and ambient / environmental light) mean that the primary component values of any colors to be mixed are insufficient for determining the behavior of the mixture. The color mixing model used by Colorigins holds some of these variables constant to simulate a particular type of color mixing experience.
Instead of using primary component values to calculate a color mixture, Colorigins uses spectral reflectance values. As visible light consists of a spectrum of wavelengths, any subtractive color can be represented by a series of data values that indicate the amount of light reflected at any particular wavelength. The source colors for Colorigins are based on a palette of Munsell Color System colors for which a data set of spectral reflectance values has been determined experimentally. The palette selection was made to maximize color saturation (as saturation invariably decreases upon mixture) while maintaining equal color value, as well as to ensure a perceptually familiar hue gradation.
