Thanks a lot for your script. Thats it, what we were looking for.



Good that helps. Then I think that probably it would a good idea to try 
to add the UI to configure it. Although Im not really a designer, let's 
see if opening the issue someone volunteers.



I wrote a little reset-script, so anybody can change everything to 
standard values (script attached).


For better understanding and testing different values i'd love your help.

The Script changes 6 values (3x color brightness and 3x contrast).
*Q: Are there any other values in gsettings that you recommend me to 
change/try to change?*



In relation to the overall color, there is only one gsetting left, 
invert-brightness, but you can configure that one with the "white on 
black" button, as that one can be configured using the existing settings UI.





The new goal is, to raise the overall contrast of black and yellow, 
because there are still some parts in some applications, that have a 
relatively low contrast. For example, some login parts of websites in 
firefox.

Hello Felix,

To benefit to the best accessibility of color I advise you to use the 
Compiz Window manager that include a module called Color Filter that 
provide many color filter schema.


To make it working you need to have compatible distribution (Fedora, 
Debian, Arch, not Ubuntu or Mint) and a desktop environment compatible 
with Compiz (Mate for example).


Let us know if you need help for this.

Best regards,
Alex.

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).


My question:
Could it be possible to implement other color combinations in the 
future? 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.

Hi apinheiro,

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?





Is there any other way to change the colors of high contrast mode?

Best regards,
Felix L.

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:

... 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.
