# John got a new dog?

I was walking down the road the other day when I bumped into my old army friend John.

He had a new dog with him so I asked him what its name was.

Now he's a big nerd of all sorts of TV shows and films but he also loves his puzzles, so instead of telling me the dogs name he said something about getting even with me and handed me a piece of paper:

I'm not sure what I did to him but it's been bugging me for a while now so I would appreciate it if someone could just tell me what the dog is called!

Hint:

Hint 2:

Both me and John spent time in a POW camp.

Hint 3:

"J-A-Y? You're spelling Jay."
"As in Jay Garrick? He's he's alive."
"But he's on my Earth."
"Hey, hey Stop, stop hey Stop look, I'm sorry."
"I don't know what you mean."
"Jay Garrick didn't come with us."

Hint 4:

Focus on the numbers more than the colours.

• The hex value of the colours from left to right: FF4C4C, FFE84C, FFFF4C, 88FF58, 4CFFFF, 4C70FF and FF4CFF Commented Jul 26, 2017 at 14:56
• @BeastlyGerbil Thanks! i use inverted colors:) Commented Jul 26, 2017 at 15:10
• Damn it. I'm 99% sure I have the solution but can't fully figure out all steps to get to it... Commented Aug 1, 2017 at 10:37
• @RottersSlave You can post a partial solution with what you've figured out to help other people! Commented Aug 1, 2017 at 10:44
• My first guess was that it's a shifted tap/knock code, but there's 6 numbers here instead of 5 :(. I'm wondering if there's another way to make it work, or another code we should be using. Hint 2 strongly points towards a POW communication code. Commented Aug 3, 2017 at 15:03

Since that appears to be the colors of the rainbow, my guess is

Roy G Biv, for one of the common acronyms for remembering the colors of the rainbow.

• Afraid not plus theres nothing about the numbers on this one Commented Jul 26, 2017 at 20:01

EDIT: Well, based off of the new hint, the answer clearly requires usage of the tap code. Good luck all.

## OLD INFO BELOW

It's possible that

John is John Pryor, a deceased WW2 POW. He was in the news a while ago for a code he used during the war. The flaw in this is: John Pryor's code is used for messages. The John in this story never gives us a long message, just a piece of paper with some numbers on it. Also, John Pryor signaled a coded message by using numbers for the date instead of fully writing out the words (10 instead of October) and you don't really see this in the puzzle.
