So was actually designing something in Freecad, and I was annoyed I couldn’t see my sketch lines…
But this is super easy to fix by changing default shape color in the part design workbench.
So shouldn’t we change the default white to more gray?
White isn’t in the default config. There the color is grey, in RGB values: 204,204,204.
Yeah, the gray is too white or too light. We should tune it to a gray on which the white lines are still visible.
Is there a chance that your light position is non-standard, I’m with Chrisb that the default colour is dark enough as is?
I can see the white lines here. Perhaps your graphics card doesn’t show intermediate colors?

It seems to depend on the default light position where there is no setting to adjust.
Even if there is no setting, I would prefer if the light position / environment lightning is not in parallel with one of the main planes.

True but changing the color is probably a lot easier 
And nobody cares probably if it’s gray or darker gray.
Still curious if this fixes the issue or whether it is not caused by the environment lightning. Here is the python script:

Btw pardesign wb doesn’t use the newshape color that’s mentioned in the preference cfg file. Which also would be nice.
Not sure why chrisb doesn’t has this isue. I have a 3060 graphics card pretty common thing.
Nope didn’t screw around with light.
Probably even contrast and luminosity tuning, there are around some test pages that will show if the monitor is correctly set to display as example shades of grey.
I had in the past some surprise when I have used these test pages, standard monitor settings were not the best, and my monitor was not the very cheap side at the time, now it is old but it is working decently.

If it is just screen tuning it wouldn’t be visible in the screenshot?
I have attached a sample file, if you edit the sketch and rotate the screen to it then it looks as this on my screens.

What about another solution — switch “Draw Style” to “Wireframe” on entering to sketch editing mode and back to previos style on closing sketch editing mode?
And is it possible to automate such style switch? (to not press shortcut each time manually)
Did you try this with a clean config?
Tried it, could someone else try the example file?
Maybe it’s a windows issue?
Since there are not a lot of Forum users on Windows I think.

I’ve experienced this issue before also on Linux, so not just Windows.
confirmed. Please retry with the attached file
cheers
The issue is in my theme files.
If I apply my dark theme it sets it too white…
Updated it!
Not a clue how this happend.
