White Vs Red Sandalwood
As per Sharangdhara Samhita, if you are preparing herbal powder for oral intake, or fermented infusion (Asava), or herbal ghees or herbal oils, white variety is to be used by default.
Whereas if you are preparing cream for external application or herbal decoction for oral intake, then red variety is the default choice.
This is probably based on the phyto-chemical affinity of the two types to different mediums — water, fat and alcohol.

Does it leave red tinge on face, when the powder is made to paste and applied externally?
Yes, it may leave slight red tinge on face. If it is bothering you, then make a very dilute paste with it, just 3 pinches of powder mixed with 2 teaspoons of water and apply in the evening.
Leave it on face for 10 minutes, wash off with water and soap.
Raktachandana usage during pregnancy:
A cup of milk is added with a pinch (1 gram) of red sandalwood powder and is administered to pregnant mother for a period of 2 – 4 weeks time. Because it balances Pitta dosha and checks bleeding, this remedy is used in cases of threatened abortion and unexplained bleeding during pregnancy. But in traditional practice, its usage is limited to just 2 – 4 weeks only, during pregnancy.
