Describe the bug
I switched over to ATC BLE using this guide. I've then changed the displays to the right type (I think) using the image uploader. 290 Gici BWR SSD for the 2.9, 213 Gici BWR UC for the 2.13 (the SSD one made it unresponsive for some reason, I don't know the differences). I've also updated everything to the latest firmware version from there just to be sure (from december I think)

If I upload hello world text from the image uploader, everything works fine and the accent color is also working. However, using drawcustom in homeassistant always reverts the accent color to black (either using 'red' or 'accent'). If I do a dry-run, the preview image will show the red image, if I do an actual run, the preview image will also show black. So somewhere in this last step somehow the color info is lost.

To Reproduce
Steps to reproduce the behavior:

upload ATC BLE firmware
Include device in home assistant openepaperlink integration directly without AP
Send simple test text or icon with red color
See error

Expected behavior
The red color to show like before

Additional context
To be fair I'm a bit out of my depth here, so it might be that I've selected some wrong options or something in the image uploader, but I couldn't find any good info on what everything means there.

Please ask this question at the Home Assistant Integration Repo. Most likely you have to update the HA integration.
