C# WPF自定义模板列表框在IsSelected上显示不正确的颜色

TLDR版本

在Windows 10上运行的WPF应用程序中，我有一个带有自定义模板的列表框，其中包括当一个项目被选中时文本前景色的规范。颜色应为#FFBF00，但显示更浅或“褪色”。如果我将颜色更改为其他颜色，我会得到相同的效果（类似的颜色，但更亮）。应用程序中的其他颜色显示正确（因此这不是显示问题）

根据我的发现（请参阅相关问题），这似乎与Windows 8（或相关的.NET framework版本）中的更改有关，我还没有找到解决方案或解决方法

以下是列表框的自定义样式/模板：

不幸的是，我没有Windows7系统来测试这一点



那么，有什么解决方案或变通办法吗？我希望避免编写一个完全自定义的控件（但归根结底可能就是这样）。Windows8的东西是一个危险的东西。关键代码段如下所示：

<Storyboard x:Key="PhaseDeselectedAnimation" Duration="0:0:0.25">
                            <ColorAnimation Storyboard.TargetProperty="Color"
                                            Storyboard.TargetName="ForegroundBrush">
                                <ColorAnimation.EasingFunction>
                                    <PowerEase Power="2"/>
                                </ColorAnimation.EasingFunction>
                            </ColorAnimation>
