Abstract
We present a method of CRT calibration useful for the efficient examination of a wide range of hypotheses about human color perception. We take advantage of the local linearity of gamma correction in cases in which the stimulus colors for an experiment lie in a limited region of color space (or in a limited number of small regions). This situation is quite common in threshold experiments. In many cases complete monitor calibration is unnecessary and inefficient. Often when only a few colors are needed in an experiment they will be calibrated individually. However, explicit calibration of every necessary stimulus color limits the range of experiments that can be performed. Our method allows for an efficient intermediate option.
