Play button color

[Luzaca]

How do I change the color of the "play" button in Stream Classic. It is currently white; I need to change the color to a darker color -or custom color.   I'd appreciate it help with this and thanks.

Classic Stream is not really customizable, and hopefully you're aware will eventually go away as part of the transition to Stream (on SharePoint).

@Kevin Crossman thanks for the response. Yes, aware of the transition. We changed our thumbnails to make the play button more visible. It is white so it is not obvious when the background is of a light color or white.  We wanted to make sure it is accessible for all individuals, so we found a solution. Thanks.
