Shiva is possibly a fair skinned god with blue throat(Neel Kantha due to poison he took to save the world).According to Sati,Shiva is the best looking god,but he couldn't care less about his looks.Most of the pics suggest Shiva is fair.
Appearance of a God changes according to people.I read some book in the past where they're suggesting that Hindus might belonged to Ethiopia or somewhere around that place who migrated to Asia.They're suggesting it because what they thought,Vishnu idols they excavated looks like African male.They claimed that over the time,appearance of gods has changed.New gods were added.

And I can assure you,there are plenty of black gods as well.

I was hesitating to post the link as it is common belief that you shouldn't mock or cross your path with this god.One simply prays that Shani God never lays eyes on you.
I don't exactly remember the name of the book though.
