Hi apinheiro,
thanks for your answers.
You wrote: "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."
I tried that, but i was only able to change the color of
the crosshair, not the color of the "high contrast mode".
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.
just a gentle ping, because as I mentioned on my last email, I'm
interested to know if this instructions helped you.
Were you able to configure the zoom for your needs based on the
script? If not, do you need some extra hints about how to use it?
