In most cases the restoration of the presented color was as a complete square, triangle, etc.  In changes from the presented color the new color appeared at a corner, or edge, or as a patch at the center.  With E. the “color flashed over the whole field and then had to be restricted to the figure.”  B. “held the outline, emptied of the old color, while it was filled in with the new.”  D. “had a clear outline, and the new color came in small blotches inside, and effort spread them out to cover the whole figure.”  For I. the “new color came sliding in from the right side over the old, which, however, disappeared as if it were moving out of focus.”  With A. the new color usually came from either the lower left-hand or the upper right-hand corner.  F. kept a clear outline and the new color came in from the right.

When E. found it difficult to create at the center the desired color, he thought of some object (garment, grass, sky, etc.) of that color and then transferred it to fill in the outline preserved at the center.  B. moved the colored figure aside and in its place put one of the desired color, moved the new figure up to the old and there superposed it.  With G. the new colors seemed of new material and there was felt to be an accumulation about the center, of old color-material.  Then he located the square outside of this imaginary debris and began again.  H. found that the colors of his own experiments, in which he used color squares framed in black, came to his mind at the names of the desired colors, and the association soon gave him the figure also.  I. located the new colors around the presented one, first all at the right; then green at the left, red at the right, yellow above, when presented blue was at the center; then yellow and green were at the upper left-hand corner, while red came from behind.  The new color ‘slid in over the old.’  It was found easier to secure the desired color when its position was known beforehand.  J. also used a similar device.  He ’turned towards the places and brought out the required color and filled the central outline with it.’  He tried to break up this scheme and got red without going after it but found himself ‘at a loss to find the colors.’  Later he succeeded so that the required color simply appeared in the outline of the old color at the center.  K. turned his eyes to corners of the central outline, then to the center, and found that this aided in developing the desired color from the corners inward.  When difficulty arose, he experienced muscular tension in body and legs and jaws.

Five of the subjects considered the change from a presented color to blue the hardest and one found the change to red hardest.  Green was placed second in difficulty by one, and blue second by the one who found red the hardest.  Three reported the change to yellow the easiest and two the change to red.

The change from red to yellow caused ‘an unpleasant sensation’ in C. and the new figure ‘had a maroon halo.’
