In the Windows Settings > Colours, you can turn on "Show accent colour on the following surfaces... Start, Taskbar, and action center", and DisplayFusion should match to the Windows taskbar.

Could you send me a copy of your troubleshooting info? Here are the steps:
 

• Open the DisplayFusion Settings > Troubleshooting tab
• Click the "Export Info to File" button
• Reply with the file attached

Thanks!

Thanks! Everything looks ok there. Could you send me a backup of your settings? (Settings > Options > Export)

Really strange, I've restored your settings and the DF taskbars have the same colour on my test system. Could you attach screenshots of the DF taskbar and Windows taskbar on your system?

Oh, I do have a thought here. Are you using the taskbar colour options in Classic Shell? If so, try disabling them and use only the Windows options.

Unfortunately it's about as close as we could get it. We can't use the same rendering API that Windows uses so we read the colour from Windows and render it ourselves.

Please let us know if you have any further questions at all.

Thanks!
