Sorry, I didn't explained myself properly: Right now there are three 
tabs to configure the zoom: "Magnifier", "Crosshair" and "Color 
effects". "Color effects" allows to change the brightness, contrast the 
amount of color, and has a "White on Black" button. FWIW, that one is in 
fact a "invert brightness" button, that is an alternative way to get 
something similar to a high contrast mode. So, what I wanted to say, is 
that at some point we had the plan to add there more functionality, like 
the one you need to specify a specific color, instead of just allowing 
to change the intensity.

Having said so, just in case, I checked again, and in fact, some of that 
functionality is already implemented, but unfourtunately there is not UI 
to configure it. So if you don't mind to use the terminal, here it is 
explained which gsettings can be modified to change the colors:

https://wiki.gnome.org/Projects/GnomeShell/Magnification#Implemented_Features

Just in case, I have attached a script that sets the brightness and 
contrast colors to yellow. You just need to open a terminal and write:

$ sh color-settings.sh

Note that script will not enable the magnifier, you still need to enable 
it. You can play a little with the values there, and the "White on 
Black" button and see if you get that you need.


Sincerely, as Im saying, there is more implemented that I remember. If 
you get the proper colors using that script, and think that the outcome 
is useful, I think that we could try to open a issue on the settings UI, 
to see if there is a way to get an UI to configure it.  So if you get 
this configured in a way that it is useful to you, I would appreciate if 
you mention that.

              too many special modes, and adding to the zoom the ability
              to do color effects. If you go to the zoom configuration
              tab, in addition to the ability to add crosshairs, you can
              see that there are some color effects tabs, and that there
              is also some built-in hight contrast mode on the zoom.</p>
