plotting - How to make this 3-D Plot Transparent?

Basically, I want to make this 3-D Plot transparent. I've already tried Opacity[]. I also want to change its color to e.g. light blue.

α= 1;
β= 1;
tmp = 0.1316;
ρ= 0.01;
t = -1.5;


fe[m_, p_] := 
 1/2*(t - 1)*p^2 + 1/4*p^4 + (1/2*\α^2*β*m^2*(t - tmp)) + 
  1/4 α^2*(β)*(m^4) + 1/2*(\ρ*(p^2)*(m^2))

Show[SliceContourPlot3D[-z, 
  z == fe[m, p], {m, -3, 3}, {p, -3, 3}, {z, -6, 6}]]

Answer

You can use ContourShading with Directives to achieve both.

 α = 1; β = 1; tmp = 0.1316; ρ = 0.01; t = -1.5; 

    fe[m_, p_] := 1/2*(t - 1)*p^2 + 1/4*p^4 + (1/2*α^2*β*m^2*(t - tmp)) + 
      1/4 α^2*(β)*(m^4) + 1/2*(ρ*(p^2)*(m^2)) ; 

 SliceContourPlot3D[-z, z == fe[m, p], {m, -3, 3}, {p, -3, 3}, {z, -6, 6}, 
          ContourShading -> Directive[Red, Opacity[0.5]]]
