Hey there, I've got some examples for you with myreds if you like? my first ones I did were my Exorcists, they were mechrite red washed with badab black then highlighted up using red gore and blood red adding more blood red to get highlights then finally adding a touch of blazing orange into the last mix for the final highlights, if you use white in red it turns pink which isn't good so using oranges and yellows will keep it red for you.

the second way i'm doing red now is a really easy method, i've bought the army painter dragon red primer in a can and used that to base the arms for my Marines Exemplar army then once they're on a wash of devlan mud to darken them slightly and highlight with pure blood red and then with a bit of blazing orange in the mix to your desired level, you may need to browse a couple of pages before you get to them in my blog but they're there i promise! :-)
