Robin handed me some color codes the other day. They don't look like anything to me though. Can you help me find her favorite shade of red?
Hint:
Once again, there are tools on the interwebz that can help! (There's a clear theme here, from the easiest pico problems, to the hardest ones in other CTFs, search engines are your friend!)
Unfortunately, making an automated tool would be more troublesome. We can use deductive guessing here though, since we know colour codes are RGB. Therefore, we are looking for a value there's greater in the first two hexadecimal digits than the rest.
7A3B00
6000C7
67C700
42FFFC
C70002 <- this seems like the most likely candidate, and it's red too!
0003C7
007A78
Therefore, the flag is, C70002.
