The boy saw Frank ocean and saw that he was a coward! Yellow on a man sometimes mean cowardness'. The blind boy went ahead to help flank understand the most important things in life, that could be more important than visions. The boy never saw the world the way someone with vision sees it, he used feeling and the experience he had when he had vision. He had nothing to do with war because he had nothing to fight for, had nothin' to do with borders cause you only see the border when you can see and sees everybody the same.
The flank thought the blind guy is missing a lot by not seeing natural wonders like Oceans, Mountains and stars but the blind boy proved Frank that he was the one who missed out a lot of things, because the blind boy had love, Hope and Faith that can move mountains! Hope I have helped in the meaning and hope someone out there has a new perspective on the blind, respect!

The blind boy saw a blue man,this man was poor but he had love he went to his house which was full of love but love wasn't the same anymore since the wife passed away
.we all know blue means love!

Blind boy saw a green girl who live a luxury life, she was a member of the green club, but she was selfish she never even thought very much about the environment but she was bragging about saving the world. Green means money and nature.
