I need help with genetics, i am really confused.

in text an 8th grader can understand.. i'm trying to comapare it to a job or roll of a recording studio.. I've looked it up, and googled it, but they don't give smooth, and if they do, its in smart smart speak. I DO NOT WANT ROUGH OR JUST ER (endoplasmic recticulum). If you have the basic jobs of the SER (smooth ER) that'd be helpful, I already know RER
thanks

I'm not talking about imagination. You know how when you close your eyes you see a mixture of different colors and little empty dots flying around? And when you shine light you see the color red.

Can the blind/color-blind people see that? Or is it always pitch black? Please answer serioulsy.
