How do I change the colour of these lines from black to, let's say, red?

ContourPlot3D[25 (x^3 (y + z) + y^3 (x + z) + z^3 (x + y)) + 
50 (x^2 y^2 + x^2 z^2 + y^2 z^2) - 
125 (x^2 y z + y^2 x z + z^2 x y) + 60 x y z - 
4 (x y + x z + y z) == 0, {x, -1, 1}, {y, -1, 1}, {z, -1, 1}, 
Boxed -> False, Axes -> False, 
ContourStyle -> Directive[Yellow, Opacity[0]], Mesh -> None, 
ViewPoint -> {0, 0, 2}]

Although researching for quite a while, I could not find the answer. Thank you indeed for pointing it out to me.
