TOYO INK 's color scheme tool that allows you to choose the best uniform combination to match the match card is being piloted in the J-League

Lioatlas ™ UFP (Rio Atlas UFP), a uniform color selection tool provided by artience group 's TOYO INK CO., LTD. (President and Representative Director Hideki Yasuda, Chuo-ku, Tokyo), has been introduced on a trial basis to the Japan Professional Soccer League (J-League). Starting in 2026, this software will be used to select uniforms with color combinations that are easy for anyone to identify for each match card.

In 2021, it was reported that there were many complaints about "indistinguishable colors on uniforms" during English Premier League matches. This happened because the dark green and red uniforms, respectively, looked the same color to the color-blind person. In addition, if the colors of the uniforms are similar or the contrast ratio is low, it may be difficult for sighted people to distinguish them.
While team identification by uniform is essential not only for spectators but also for players and referees who need to make split-second decisions, it has also been an issue in the J-League as uniform combinations can be difficult to distinguish depending on the match card.

TOYO INK 's newly developed "Lioatlas ™ UFP (Uniform Palette)" allows users to easily select an easy-to-identify uniform combination for each match card from a database of uniforms from all 60 clubs in the J-League. It also has a design mode that suggests colors that are easy to identify when designing new uniforms.
By realizing uniforms that are easy for anyone to identify, we will contribute to creating an environment where everyone can easily enjoy sports.

About color combinations that are difficult to identify

Difficulty in identification due to differences in color vision types

There are three types of cones: the "L cone" that senses red, the "M cone" that senses green, and the "S cone" that senses blue. The color vision group (type C) with three types of cones accounts for the majority, but in Japan, about 5% of men and 0.2% of women see colors differently from type C due to the absence of some cones or the deviation of spectral sensitivity. This has led to the fact that there are color combinations that are difficult to distinguish depending on the color vision type.

Difficulty in identification due to lack of contrast

The human eye recognizes colors and shapes based on the difference in brightness between the object and the background. Therefore, if the brightness difference is small and the contrast ratio is low, the brain will not receive enough information to distinguish between the two, leading to increased visual fatigue and difficulty in identification.
