# Density type puzzle 2

Here's another puzzle of this type. Perhaps my next one will be complex enough to require the full $$72$$ x $$72$$ size.

• Is visual the only applicable tag here? The original post said that the tags should indicate the techniques involved to find the solution – HTM Oct 19 '19 at 2:00
• @PiIsNot3 I'll add "Cipher" though it really isn't. It's a communication protocol (big hint!). – Jens Oct 19 '19 at 9:11
• Possibly that hint was too big. – Jasen Oct 19 '19 at 10:14
• @Jasen It probably was. :) – Jens Oct 19 '19 at 10:17

The symbols look like

morse code - .. ... .- .-. . -.. .... . .-. .-. .. -. --.

but decoded it spells

TIS A RED HERRING

but it's a clue to the steganography:

If blue is long and yellow is short and a notch is a pause

It says

-- --- .-. ... . .. -. -.-. --- .-.. --- .-.

which translates to

MORSE IN COLOR

• Ugh, I got the red herring message but didn’t know what to do with the notches. Good job! – HTM Oct 19 '19 at 10:18
