    $\begingroup$ I'm a little way through and it seems clear what kind of thing is happening. Nice! $\endgroup$ – Gareth McCaughan Mar 2 '17 at 15:57

    $\begingroup$ The comment I was going to make was: I'm pretty sure there is in fact a simple nonogram in this puzzle. (And lo, there is.) $\endgroup$ – Gareth McCaughan Mar 2 '17 at 17:18

Final answer is

or perhaps I should say


I confess that I only bothered going this far by strict logical inference

before allowing myself to make the obvious assumptions about the structure of the solution, leading to this (where white and yellow should now be treated as equivalent):

whereupon it's clear how to get to the solution at the top.

    $\begingroup$ After you had mentioned the "nice thing" in the comments I noticed the positions of the empty rows and columns and suspected a nested nonogram (Nonogramyoshka?). But you had a headstart of an hour and I had little hope of beating you. Nice, indeed! $\endgroup$ – M Oehm Mar 2 '17 at 17:21
  • $\begingroup$ Eek! Let me check. $\endgroup$ – Gareth McCaughan Mar 2 '17 at 17:31
  • $\begingroup$ Oh yeah, sorry, most of them are one column further right than they should be. Fixing 'em properly may be a little nontrivial but I'll try :-). $\endgroup$ – Gareth McCaughan Mar 2 '17 at 17:32
  • $\begingroup$ OK, fixed. Sorry about that. $\endgroup$ – Gareth McCaughan Mar 2 '17 at 17:39

Gareth McCaughan solved this, but here's an animation of the solution:
