RGBRGBRGB
User @captainmaku figured out that he has to use the RGB code of the colors red, green and blue from hint 1. He went further and found out that he has to use the pattern given in hint 2 to put the RGB code in the right sequence.
By doing so he was able to decode the message hidden on defuse.ca and got a link that contains this picture.
Unfortunately there were some problems I fixed quickly. The picture on Steemit manipulated the image and changed some RGB values. After uploading a raw file of the picture my detective skilled Steemians were able to solve it. I payed everyone who tried to solve it within the first minutes and wasn't able 10 Steem as a redemption. Won't happen again!
@jeppex1 did what seem to be impossible. The Steemians spent hours to solve this one. Inside this picture was another hidden. This method is called Steganography. If you want to know more read my post Hiding sensitive Information: Steganography.
But how did he do it? After I saw that my agents were not able to extract the data, I uploaded another version which was easier to break. I gave them another hint to use mobilefish.com to decode the picture. All they needed was another password.
The filename was coversecret and another hint from me was Run backwards. They tried to use this password and it was almost right! They tried all possible passwords until 
With tercetrevoc he was able to extract the last piece of the puzzle:
Great work and congratulations to the winner and all who participated. @captainmaku you get 10 Steem for the first hint! Don't miss the next Steemit Crypto Challenge and be prepared.
