Change color of Slider marker

URL of experiment: In general.

Description of the problem: Is there any way to change the color of the Slider marker circle from Red to anything else?

Hi @huppfi, you could change the appearance settings in the slider componenet dialog to "white on “black”. Alternatively, in a code component.:

slider.marker.color = 'green'

The problem is that my background is white so I need the circle to be black or grey.

Also the code does not seem to work in an Online Study.
