Change splash screen background color?

I just created my first splash screen and as you can see there is black showing at the top and bottom where my image doesn’t fill the screen. I used all the image sizes RAB suggested. I could probably change the image size to fit my particular screen, but that won’t work with every phone.

Is there a way to change the background color behind the splash screen? If I could make that black turn the red in my image it would be perfect.

Or is there another work around for this?

Thanks a ton!

I don’t have time to test. I think the aspect ratio of the splash screen image is 16:9 but some phones like mine and yours are 18:9.

I hope someone knows differently but I think you are stuck with black bars.

Thanks. I may try uploading 18:9 images as well if that’s possible.
