You're under attack! Who by, you may ask? By the Asthmatic Enemy Omnivores, of course! Why? Irrelevant!

You've just found a bomb that they planted near your headquarters, and the only way to disarm it is to put in the correct six letter code. The only hints are a cryptic poem (with horrible meter and slant rhyming), and an image with a large array of letters in red, green, and yellow. The image also has what appears to be some guides, but otherwise it is rather unclear what's going on.

Before you proceed, it seems you must find
A background image, to match with the lines.

Then take the letters, that blend in right
And order them round, from naught to two-pi

Where have I seen these colors before? (Click to enlarge/download. You'll probably need to!)

  • $\begingroup$ As a point of interest; the personages in this puzzle are the Asthmatic Enemy Omnivores, You, and (from the point of view of the puzzle text) @DqwertyC is implicitly "I". And the only question explicitly asked is "Why?". Yay for secret vowel puzzles! $\endgroup$ Commented Jan 24, 2018 at 10:15

If we

overlay the PSE logo so that some of its pointy angular bits match the guides, we get this: enter image description here

and hence, following instructions

by reading letters that match their local background colour, anticlockwise from the east, NOW YOU MUST AGAIN GO ROUND THIS TIME READING RED ON GREEN. (These letters are the ones I have circled in the unreadable image above.)

This in turn yields

by reading in the same order but looking only at red letters on green background, NOW LOOK AGAIN FROM BASE TO TOP READING SUN WITHIN THE VOID which I take means yellow on not-part-of-the-logo (the other obvious interpretation is yellow on black, but there isn't enough black).

This yields


and this yields

(with some pain because distance to centre is not so visually apparent as one might like) ITS SO META EVEN THIS ACRONYM

so the required 6-letter code is clearly

ISMETA (see here for background).

Credit where it's due: ffao posted a partial answer before I posted anything, but on my honour (should I happen to have any) I declare that I had already got further than that when he posted it :-).

  • $\begingroup$ As always, I am amazed by how fast you can solve these! Fun fact, the "Asthmatic Enemy Omnivores" is an anagram for the second-to-last step. $\endgroup$

  • $\begingroup$ I expected you to have gotten further than I did; you didn't have to waste time composing an answer, for one. But using transparency this way looks much smarter than what I did too. $\endgroup$

Partial answer

The image has some suspicious looking guides, looks like three right corners but they do not line up to form a rectangle. Where have I seen something like this?

The Puzzling logo! (I guess "red, green and yellow" was a hint to this too, but I only realized after I'd found the correct image.)
enter image description here

Following the poem, let's overlap the background image with the lines:

I also only left the letters that matched the color of their corresponding region, because we should take "the letters that blend in":

enter image description here

Reading from 0 to 2-pi (aka start from right, read counter-clockwise):


I believe this is telling us to ignore yellow, but reading the same way doesn't give me a coherent message, assuming I did it right.
