Hi There,

There are a couple of differences with slides for online use at the moment that means they need some tweaks through code.

For example they don’t allow a start value (as you identified).

Here is a demo that might help get started with what you need: [marker\_color [PsychoPy]](https://run.pavlovia.org/lpxrh6/color_slider_demo/)

If it looks helpful you can access the files here [Rebecca Hirst / color\_slider\_demo · GitLab](https://gitlab.pavlovia.org/lpxrh6/color_slider_demo/)

Hope this helps,  
Becca
