The cone visibility from the CCD detector array plane in the calibration channel of wide field planetary camera II (WFPC II) is analyzed, using APART, for three representative wavelengths as characterized by indices of refraction. The light pipe walls are visible from the corners of the equivalent CCD detector array when imaging with the smallest index of refraction, n = 1.375. Painting the inside of the light pipe walls will result in a decrease in their visibility.
