How to change the Modern Player colours other that "Dark" & "Light" theme in Articulate Storyline 360

Yes, I agree with everyone above me. I love the look of the modern player, but I definitely need a way to change the background screen color. The Light color scheme (which only gives you white as a background color) is too white. This is a problem when I have a screen image that is predominantly white on the edges, so the content floats awkwardly on the display. To add an outline around the edges of the screen size ruins the look of the modern player. And changing the player to Dark is too dark and harsh. I would like to be able to change the background to a light grey color, so my white screen images look like they are framed by a lovely grey frame, or it would be nice to be able to change the background screen color to our corporate brand color. Yes I know I've seen where one can take the Classic player and change everything to make it seem invisible, but that seems like an awful lot of extra work to recreate something that already exists, and that just needs some more customization options.
