    public String getName() {
        return "MyCustomTheme";
    }

    @Override
    public void applyTheme(ImGuiStyle style) {
        col(style, ImGuiCol.WindowBg, new Color(0xFF1a1a2e));
        col(style, ImGuiCol.Button, 0.2f, 0.3f, 0.8f);
        padding(style, 8.0f, 8.0f);
        rounding(style, 4.0f, 4.0f, 2.0f, 4.0f, 4.0f, 4.0f, 4.0f);
