Custom view in SwiftUI reuse it in another view but need to have that view change properties of custom view like a button text color

[directx]

I created a custom login view. I use that view within another view. I want the view using it to be able to set something like a color on a button. I tried doing this with passing color in the init and I was able to get that to work. This did not feel very much like swiftui style. I tried adding a method instead and calling the method and the code seems to run but does not actually change the color. My question is am I doing this correctly with the method and is that the best way or should I go back to using init or something else. Thanks.

Custom login view:
‘’’
public struct LoginView : View {
@ObservedObject var keyboardHandler: KeyboardFollower

@State var username: String = ""
@State var password: String = ""

@Binding var presentingLoginModal: Bool

@ObservedObject var userDefaultsManager = UserDefaultsManager()

let loginService: SoCoLoginService
let defaults = UserDefaults.standard
@State var loginTextButtonColor: Color = Color.blue

public init(loginService: SoCoLoginService, presentingLoginModal: Binding<Bool>) {
        self.keyboardHandler = KeyboardFollower()
        self.loginService = loginService
        self._presentingLoginModal = presentingLoginModal
    }

public var body: some View {
    VStack(content: {
        TextField("Username", text: $username)                
            .autocapitalization(UITextAutocapitalizationType.none).textFieldStyle(RoundedBorderTextFieldStyle())

        SecureField("Password", text: $password) {
            self.loginUser()
        }
            .autocapitalization(UITextAutocapitalizationType.none)
            .textFieldStyle(RoundedBorderTextFieldStyle())

            context.localizedCancelTitle = "Enter Username/Password"
            var error: NSError?
            if context.canEvaluatePolicy(.deviceOwnerAuthentication, error: &error) {

                } else if (context.biometryType == LABiometryType.touchID) {
                    reason = "Unlock using Touch ID"
                } else {
                    reason = "Log in to your account"
                }
                context.evaluatePolicy(.deviceOwnerAuthentication, localizedReason: reason ) { success, error in

                            self.loginUser()
                        } catch KeychainError.unhandledError(let status) {
                          print("Unhandled error of: " + status.description)
                        } catch KeychainError.noPassword {
                          print("No password in keychain")
                        } catch {

my other view:
