Usually the diffusion color would be about usual skin-color we see every day, then the transparent color would be a pink or red color.
From there its a matter of tweaking the amount of transparency, and the saturation and brightness of the transparent color. Also, if the transparent color doesnt look quite right, you could try playing around with the hue. The blurryness of the transparency should be very high. The amount of blurryness is controlled with the brightness of the specular halo.

Currently most likely, your object is too transparent, and the transparent color is too orange instead of pink/red-ish
