Rhino.Input.Custom.OptionColor bug on Mac


there seem to be 2 bugs in the method Rhino.Input.Custom.OptionColor on Mac (Rhino 7.9). Please run the attached example to reproduce:

OptionColorBug.py (806 Bytes)


  1. Run the script, change the white color in the prompt to red
  2. The color field does not update, it stays white


  1. Run the script, do not change the color and click on “Done”
  2. The color returned is always 1 to small for the R component, it prints 254, 255, 255
  3. This seems to happen with other colors too

above example works fine on Windows.


Hi @clement,

I’ll have a look at this:
