[Closed] custom dotNet Toolstrip separator ?

is there any way to override to change the color of toolstrip separator in “System.Windows.Forms.ContextMenuStrip” , I try using on paint but it appear when I using ecliprect , it became bold line not thin line …I just want to get rid of imageborder on the left side and change the color of the separator to the way I want…

this is the previous code result…

:: note , the first picture show that I want to colorize the image border on the left side to match entire toolstrip background !

:: note , the second one is I want to change the color of toolstrip separator to match the green color one… like the picture below
