As long as self recs are welcomed :-)

#3. My 2013 BB, The Colors of My Life hopefully will match your request for Blind!Jensen--although he's not totally blind (yet). Here's the summary:

At age twenty, "Blind Artist" Jensen Ackles became a successful, world renowned Abstract Impressionist painter by painting what he saw. However, fourteen years later, Jensen feared that what was left of his poor eyesight was coming to an end sooner rather than later and wanted his work to carry on after his colors faded to black. Jensen takes on an aspiring, talented young artist, Jared T. Padalecki, as his apprentice.

"It might be a bumpy ride, but I swear, it'll be worth it."

"I know what it looks like, but this is how I see it."
