graphics – Assign a color to VectorPlot

I want to set all the lines in a VectorPlot a specific color, like Red. I am using some of the new options for VectorPlot as my code below illustrates. Using VectorColorFunction -> Red does not solve my problem.

Thank you for your assistance.

VectorPlot[{1, t - x}, {t, -2, 2}, {x, -2, 2}, VectorPoints -> 17, 
VectorScaling -> Automatic, VectorSizes -> 1.2, 
VectorStyle -> Arrowheads[0], VectorColorFunction -> Red]
