Karen Taylor created the Color Vowel® Chart at the University of Maryland in 1999. Karen’s international teaching assistants appreciated the way it helped them to pronounce academic and technical vocabulary.
Shirley Thompson piloted the Chart with international students at George Washington University. Quickly recognizing their shared interest in pronunciation and brain-based learning, Karen and Shirley continued developing the Color Vowel® Chart together.
Dr. Robin Barr, Linguist In Residence at American University, soon joined the effort, testing the simplicity of the Chart against the complexities of phonology. Time and again, she has found that the Color Vowel® Chart delivers– providing linguists, teachers, and learners with a touchstone for describing the deep rules of spoken English.
Laura McIndoo, an ESL teacher at Central New Mexico Community College, encountered the Color Vowel® Chart at a conference in 2013 and instantly recognized its potential. With a talent for graphic design and a love of game-based learning, Laura created the spoken card game known today as Color it out!
Color it out! was an immediate hit with learners and teachers alike. It drew the attention of a friend in the tech industry, and a new company was born in 2016. Blue Canoe's mobile app combines the patented Color Vowel® method with speech recognition and machine learning to provide people around the world with access to a virtual English pronunciation coach, a perfect complement to Color Vowel classroom instruction.
All the while, our passionate community of inquisitive teachers and learners has made Color Vowel® what it is today: a wonderfully multi-modal, brain-based way of teaching that connects the spoken and written forms of English with unprecedented clarity, raising profound implications for language identity, pronunciation, vocabulary development, reading readiness, and so much more.

Color Vowel® bridges the gap between spoken and written English.
"Long" and "short" are misleading terms.
Vestiges of Middle English, 'long' and 'short' are mostly meaningless in the context of Modern English.
Color Vowel® takes a sound-based approach that English learners can immediately put to use: do is BLUE, does is MUSTARD, and don't is ROSE.
English is not spelled phonetically.
Cough, tough, though and through look similar but all sound different, while words like do, you, through, new, and shoe can all feature the same vowel sound despite different spellings.
Color Vowel® moves beyond 'sound it out' and teaches learners how to color it out.
English is a stress-timed language.
Without training, teachers and students often remain unaware of stress, instead working fruitlessly on the surface features of pronunciation, overlooking stress and rhythm as the main predictors of comprehensibility.
ELTS builds sound awareness training into every Color Vowel® course and workshop.
