So I'm having 'issues' downloading the latest haks for Hala (its an internet thing nothing I can fix until I visit a friends and use his interwebz for a bit) which means I can no longer run Jestin over to Arkaz, it is so much fun here after all

So I figured I'd roll an alt here ( I do so suffer from alt-ism) and Tiefling interested me.
Of course I would like to get it right though. I've searched the forums, checked the Arkaz wiki and I'm close to rolling him up, but the only in depth lore I have on the race is from the FR wiki.
http://forgottenrealms.wikia.com/wiki/Tiefling
Skin Colour - The FR wiki states "Pale to dark brown, ruddy to brick red"
I don't want a bright red character. Apart from not being allowed, it would be immersion breaking for me and others, and look stupid.
That said I like the idea of having a red hue to my skin colour, I have checked all the skin tones and found one that doesn't look out of place, is this allowed or are the skin tones different for Arkazian Tieflings?
Eyes - Again the FR wiki mentions Tieflings can have solid orb colours, one of these being red. I dont want a solid red orb eye, but I would like the iris to be red.
And any other basic info on how they would differ. I'm certain I'll learn most of it as I go along but I'm really just looking for things that won't force me to have to remake the character / effect other players / break the cheese barrier by over 9000!
(Also I couldn't find it, but are there any restrictions on playing a Blackguard character? not that I have that planned for this character, oh no other players, look away now...

Thansk for any reply!

P.S.
This is my brand new shiney Arkaz forum account, because I changed all my stuff and things, and now I dont remember any of my log in details for my old account, to be fair I made it liek 5 years ago and I cant even remember what i wrote at the start of this post... Not to worry, I like this one, I think Ill keep it.
