Message Background Color

If you want to change the standard SwiftUI message bubble colors, update chatBackgroundOutgoing and chatBackgroundIncoming in the ColorPalette when creating StreamChat.

var colors = Appearance.ColorPalette()
colors.chatBackgroundOutgoing = .red
colors.chatBackgroundIncoming = .white

var appearance = Appearance()
appearance.colorPalette = colors

let streamChat = StreamChat(chatClient: chatClient, appearance: appearance)

These values are single UIColor entries. If you need a gradient or a fully custom bubble style, provide a custom message view instead of relying on the default bubble colors.
