Unreadable texts

I bought a big iMac because of the big screen. I have macular degeneration and glaucoma and I needed to see the screen. Imagine my surprise to see most of the text displayed in a grey color (or pale pastel colors). These are so hard to read, expecially when a transparency is added. I would like to suggest that you make a fix so us older people can change the text color to black--in a serif font--so we can read it. I am looking for suggestions if this option is available now.

thank you.

I too struggle with the new tiny font use in 10.11.1. I am deeply disappointed and frustrated towards Apple's lack of understanding UI design in regards to us who are visually impaired. Zoom was never finished, its just a brute force scalling of pixel data. I am forced to spend a lot of time writing devs to support larger font size in their app just for me to use it. :-(
