Are Blood Oranges actually that red I have tried 2 different brands of Taroccan blood orange and I have also had some Moro ones but none of them are that red like you see in pictures. Do I need to let them ripen or is it just hard to get ones that red?

The ones I have had have a reddish tinge but still look like a normal orange. Thanks
The simple answer is they can vary in redness. That would depend on the conditions they were grown in and the particular sort. Generally blood oranges are a deep (blood) red and lack the yellow tint of the other oranges. Your experience sounds perfectly normal. 
Hope this helps :)
