ColorRevealer changes color and tensity to indicate hesitations and changes hue to review writing progress. When user writes with very little hesitation, the layers behind the text appear as a pale green; when user repeatedly delete and correcte words, the layer turns to blue and purple.

Color Revealer allows users to control the mapping of colors to their writing activities and provides an adjustable timeline that lets them scroll back through earlier stages in the writing process. In above figure, the user needs additional time and has adjusted the time scale accordingly.
