## Solution

We have [html page](ctfcoco.html) with table, that draws image using background colors of cells.

Looking more closely at cell classes, we can see unused "Co" names.

Now we can make the [script](solver.py), that removes all "CoCo\<x\>" styles and adds color to "Co" cells. Result page contains flag.
