These word charts are modifications of the ones above. Some colors have been changed; the sound/chart that is to be used in conjunction with these word charts can be seen on this site under the "sound/color charts" tab, titled "A modified Sound/Color Chart (2014)." The modifications in these new word charts borrow much from the work of Piers Messum and Roslyn Young, who have developed their own set of charts that you can see here.
