Description
The following bug report has been submitted:
Platform: macOS-14.8.3-arm64-arm-64bit
ChimeraX Version: 1.11 (2025-12-17 06:45:39 UTC)
Description
In version 1.11, the color scheme for the Volume Viewer became quite harsh for eyes in dark mode. Big white histgram on top of the black background is really unpleasant. Please see the attached picture. The way version 1.10 handled it was much better, even though it could use a little more contrast.
