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

```auto
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.

Hello there,  
Did you find a solution in the end? I can’t find any way to make the tick/answer visible on my slider. The four possible circles/answers always show up white online, only the labels change colour, and still no visible marker for the selected answer.  
I also saw that it was an issue with the “Force end of routine”, but I would like to keep that option.  
Does anyone have the solution to this?  
Thanks

Does anyone have a solution for how to do this online? so far, selecting ‘triangle marker’ seems to work because it is red by default so shows up on a white background.

Hi @haaleemur, see [this post](https://discourse.psychopy.org/t/psychopy-2020-2-2-did-we-lose-slider-code-component-fx-slider-buildslider/15819/8) that will work for at least version 2020.2.2 & 2020.2.3 to change slider marker color online.
