Equal contrast tint progressions for computer cartography

Creator:: Bernert, Joseph A.
Abstract:: A psychophysical bisectioning experiment was performed to evaluate equal steps within tint progressions on a high resolution graphics terminal. In the bisectioning experiment each respondent partitioned a tint progression by interactively defining colors that were perceptually equidistant between two previously defined colors. Twenty test subjects performed the test on the...
