Choosing a Dark or Light color scheme resets some colors in viewports

8.29.26063.11001, 2026-03-04

Shouldn’t selecting the Dark or Light color schemes (in Rhino Options > Appearance > Colors) affect only the chrome of Rhino, and not of anything that can be displayed inside viewports? The color settings below are ones that change with a color scheme selection, but I think should not:

Viewport colors

  • Background
  • World axis icon X
  • World axis icon Y
  • World axis icon Z
  • Layout

Object display

  • Selected objects
  • Locked objects
  • New layer

Interface objects

  • Feedback
  • Tracking lines
  • Crosshair

Widget colors

  • U-axis
  • V-axis
  • W-axis

I determined the aforementioned by

  1. Changing all the colors in Rhino Options > Appearance > Colors to red.
  2. Selecting Dark or Light on the same window.
  3. Clicking OK.
  4. Returning to Rhino Options > Appearance > Colors so that the General category is also displayed.

The image below is the result, which means the colors that are not red are the ones changed when the color scheme is set to Dark or Light.
