Change scrolls color

Hi!

I have a dark style for my text editor but I didn't find any way to change the scrolls color. Any help?

This is my code:

SyntaxEditor editor = new SyntaxEditor();

editor.IsLineNumberMarginVisible = true;
editor.CanSplitHorizontally = false;
editor.Document.IsReadOnly = true;
editor.Document.TabSize = mToolInfo.TabSpaces;
editor.ZoomLevel = 1;

editor.Background = mColors.BackgroundBrush;
editor.SelectionMarginBackground = mColors.BackgroundBrush;
editor.OutliningMarginBackground = mColors.BackgroundBrush;
editor.Foreground = mColors.FontBrush;
editor.LineNumberMarginBackground = mColors.LineNumberBackgroundBrush;
editor.LineNumberMarginForeground = mColors.LineNumberFontBrush;

Thanks in advance!
