Possibility of hybrid light/dark themes?

Is there any way to make hybrid dark/light themes like Discord's light theme seen here?

I've tried to do so but it seems the text all must be one color. Is there a workaround for this? Has anyone been able to make a theme like this?

you'd probably have to pick a gray font that's in between black and white, contrast wouldn't be amazing but it wouldn't be terrible
