Tanget Properety Overide My Material In Viewport

[eternal art]

I'v an object with tanget propert apply to it for normal map , my problem is : it's force the viewport to display it's color instead of the material color ?
Is there anyway to disable the tanget color from the viewport ?

p.s : I'v tried all the options in the OpenGl Display in the image clip of the object , but nothing work .
hope my question is clear .

OMG ... i find the solution by chance after writing this thread ..
For anyone face this problem : Just put any value (Like AAA or anything ) in : Vertex Color Display Property in the OpenGl Display Tab , then xsi will ignore the vertex color and show material color or texture .
