Dream About Helping Color Blind Man With Tv Settings

In my dream last night I was a bartender serving drinks to customers. One comes up - an elderly man with a grey beard, a navy down coat, and a sad face. He says to me "This is the second TV I've bought from them - but they never work when I get them home half of the options on the menu are missing. He leaves the bar to use the restroom. I look over to see where he was sitting there at a table next to an empty chair was a chubby man with a black beard sitting next to a large TV (the one he was trying to sell the elderly man). I saw another large man sitting nearby say out loud to the bar. "Can you believe it? The way some people like this would take advantage of an old man. I began to fear for the safety of the black bearded salesman who was just sitting there bewildered and taking the abuse. I walked over and looked at the screen. There was a menu - and it looked like all the items were there but the way it was displayed there were white and red letters on a black background. The red letters looked very dim. "I wonder if this man is color blind" I said to myself. I asked to see the remote. "I think maybe if we adjust the color or the contrast - we might be able to make it so he can see. So I turned up the brightness, and the contrast. I'd also heard that color blind people have a hard time seeing blue so I shifted the hue away from blue and more toward the red end of the spectrum. I wasn’t sure if this was right because the letters on the screen were red and white - there was no blue. But they were also dim - so maybe the red had some blue in it. I wished the man was still at the table so I could ask him questions while I made the adjustments - but the only thing to do was to wait til he got back and see.
