Connect for Lemmy App

Hey, just wanted to say i love the app and all the customization options. I was wondering though if theres a setting to change the background colour used for the top and bottom bars for images that dont fit the full aspect ratio of the screen. As of now it seems to be using an 'average' of the most dominant colour in the image which is usually very nice, but im using a dark theme and it can be quite jarring, especially at night, when the image is say a twitter screenshot, which gives very light grey top and bottom bars. Ideally I'd like to keep the average colour background for most posts but be able to set a 'minimum' brightness that is used for bright images, but it would also be nice to be able to just set a default background color. Sorry if this is already in the settings somewhere and ive missed it. Thanks
