Solution

This task is about cryptography, and the image describes a cryptographic algorithm. There are three boxes in the image, one P-box, one S-Box, and one X-Box. These refer to permutation, substitution, and XOR, respectively. Using the colored lines, you get an example of the algorithm. Three colors can together be represented as 9 bytes, RGBRGBRGB. Using this, you can see input and output to each of the boxes, and figure out what happens inside them. The first box moves the bytes around in the 9-byte word, the second box substitutes each input byte for another one - the pattern is that the hex is reversed, and the last box does XOR with a secret internal 9-byte word. Once you have figured out the inner workings of each box, you can put any 9-byte word into the algorithm to get something else out. If you input the name of the task "ALGORITHM", the result is "mindfucks".
