Color-coding was introduced in 1890 as a learning tool and further developed in 1966 to teach phonics. Research has found that color-coding is an effective multisensory technique that uses color to scaffold, cluster, and associate content to improve memory and learning for all types of students. Studies show color-coding helps organize information and increases the ability to learn irregular words and grammar. Color catches attention and allows processing of up to 70 same-colored items, making it a useful tool for behavior management, organization, writing, reading comprehension, and other academic areas.
