On the Subject of Triple Vision

I went to my optometrist and he told me I have 20/20/20 vision. Is this that third eye I keep hearing about?

On the module is an 8×8 grid of RGBCMYWK color panels. This “image” is actually an XOR of three of the images below. To solve the module, correctly identify all three images.

To XOR two images, simply XOR the color channel values of each pixel on the first image with the pixel at the same position on the second image.

Ex: A1 on image 1 is red; A1 on image 2 is magenta; 100 ⊻ 101 = 001; the resulting image is blue on A1.

To XOR three images, simply XOR any two of the images, then XOR the result with the remaining image.

Once all three images have been identified, take each image’s position in reading order in the chart below, add them together, and count that many cells on the module in reading order, wrapping around if necessary.
