Why is the Standard Celeration Chart printed light blue?

Ogden Lindsley (1972, Page 9) named Precision Teaching because "what was really new in our procedure was precision, we decided to use that as an adjective in front of whatever it was one was doing: hence in our case, "precision teaching." Lindsley (1971) hoped that the standard recording and charting system would be used throughout the behavioral fields as Precision School Psychology, Precision Social Work (Green & Morrow, 1972), Precision Speech Therapy (Johnson, 1972), and so on. The field experts would keep their name as the noun and use the adjective "precision" to describe the method standard to all.
