アイコンの色を変えたいです

Question

ネットに載っていたサンプルコードを使って下側にあるTabbarを作ったのですが、アイコンの紫の色を変えたいです。
どこをいじればアイコンの紫の色を変えることができますか？ コードも長くなってしまいすみません。。。。
素人ですみません。。。。

このままではコードが読みづらいので、質問を編集し、<code>ボタンを押し、出てくる’’’の枠の中にコードを貼り付けてください

[JinTokunaga]

かしこまりました！
少々お待ちください！

[JinTokunaga]

貼り付けることができました！

Answer 1

すでに解決したようですが、せっかく書いたので貼っておきます。

enum Defs {
    // 略
    static let accentColor = Color(UIColor(red: 0.553, green: 0.455, blue: 0.929, alpha: 1.000))
    static let backgroundColor = Color(UIColor(red: 0.945, green: 0.969, blue: 0.984, alpha: 1.000))

ちなみに、UIColor を #colorLiteral に変えると Xcode 上で直接その色を表示・編集できます。
参考: UIColorの定義はすべて#colorLiteral使ってみることにしてみた | by mono  | Swift・iOSコラム | Medium

テキスト表示したい時は、Command+/ でその行を一時的にコメントにすると良いでしょう。

Answer 2

enum Defsに含まれるaccentColorですね。

    static let accentColor = Color(UIColor(red: 0.553, green: 0.455, blue: 0.929, alpha: 1.000));
