‘Color Universal Rubik’s Cube’ by kyo takano
Whereas Rubik’s Cube continues to be popular around the world, color blind people still cannot fully enjoy solving the puzzle. Indeed, since its invention by Professor Ernő Rubik in 1974, the cube has generally come in the same palette of six colors (white, yellow, red, blue, orange and green) – an unattainable combination for those who perceive it in the world. different shades. In light of this, designer Kyo Takano offers the “Color Universal Rubik’s Cube”, a colorblind-friendly alternative to the original puzzle. “With this design, everyone can enjoy the Rubik’s Cube, regardless of its color vision characteristics,” assures Takano.
The recreation of the Rubik’s Cube palette involved extensive research into color blindness. Kyo Takano (see After) shares some of his findings: ‘For example, the combination of green and orange is barely distinguishable for a red-green color blind person (Deutan & Protan). Even for those who are not color blind, orange and yellow have a very similar hue. Perhaps the random color scheme implemented at the start of popularization has continued to this day, only as a simple convention.
a new and improved six-color palette
Based on the research, the proposed design reconstructs the traditional Rubik’s Cube surface by adopting the latest color theory guidelines. By searching for the best combination of tones in the perceptual color space called HCL and verifying them through visual impairment simulations, Takano has assembled an optimal palette of six colors that allows everyone to have fun solving the puzzle.
