How does vnc behave if you do a manual VNC installation?

Doesn't seem to be caused by VNC. Manually (qemu/x86_64) all colors are fine and https://openqa.suse.de/tests/1891865#step/welcome/1 also confirms it. For the sake of completeness, let me check s390x too.
This leaves the X/IceWM as leftover suspects, right?

Yes, I suspect the same. So far we accepted that by creating specific needles.
Would be cool if we find a way to tweak the X server to show the same color range. Maybe you find something during your research on this?
Tested again on s390 kvm with manual VNC connection -> 0xffffff, meaning: works.
hmm, can you bring up test system into this screen so I can do some experiments myself? In dubio take a grenache LPAR :)

guess you already know the PW to loewe ;) Please leave it in a workable state without hot-patches since other engineers may require the resources configured on there.
as I suspected: the vnc server of the product defaults to 16bit pixels - which means a natural colour reduction. 4 bits for red and blue and 8 for green - and you can see that the vnc image is a little greener than it should be :)
The trick is to default to full colour (as vncviewer does), but there is no negotation implemented in os-autoinst. So use depth => 24 in the console setup of 'installation'
- Project changed from openQA Project to openQA Tests
- Subject changed from Colors on remote-backends are different to "native" qemu jobs to Change colour depth of product VNC from 16 to 24
- Subject changed from Change colour depth of product VNC from 16 to 24 to [functional][u] Change colour depth of product VNC from 16 to 24
- Category set to Infrastructure
- Target version set to future
I guess it's "infrastructure", or is it?
- Status changed from New to Rejected
- Assignee set to SLindoMansilla
The color differences are not visible anymore:
Cool! Some maybe something actually fixed this? What I see though is slight differences in the font rendering but the important part is that the very same needle is used in both cases.
