Hi apinheiro,
thanks for your answers.
You wrote: "If you go to the zoom configuration tab, in addition to

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?
Is there any other way to change the colors of high contrast mode?
Best regards,
Felix L.

Hi there,
I really like the accessibility options a lot.
Unfortunately the "high contrast" mode only has the automatic
color black and white (or vice versa).
Yes. Some history: at some point the people involved with
accessibility decided that it would be better to not add 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.
So ...
My question:
Could it be possible to implement other color combinations in
the future?
... yes, in theory it would be possible to implement more color
combinations extending the color effects that the magnifier
already have. Unfourtunately, there isn't anyone working on the
zoom actively. It would be needed to someone steps forward and
volunteer to keep adding features.
Visually impaired people can cope with very individual colors.
My mother, for example, uses bold yellow lettering on a black
background.
The default "high contrast" mode (black-white) unfortunately
dazzles her a bit too much.
Have I perhaps overlooked something and the setting for the
color selection is already there?
I am looking forward to your answers/ideas.
Best regards
Felix L.
