Quick question about beef steak colour

[BlackDragon]

Hi all,

Im not very knowledgable with food, and couldn't find much when I googled. I've got a sirloin steak here that has been in the fridge for a 3 days and the sell by date is the 24th of July. So it should be fine, but I was slightly concerned to see patches of gray/browness on the steak. Does this mean the meat has gone off? I smelt a bit of the meat that I cut off and threw away which had a bit of brown on and it smelt fine so it didn't seem to have gone off. If it hasn't gone off, then what is this colour?

Cheers!

Ok cool, I didn't really think to smell it before hand before smothering it in a bit of marinade. But I wasn't overpowered by any sort of smell so I'm hoping it is not off!

Cheers for the help

Well I cooked it for about a min on each side, then an extra 30 secs on one side. Although I discovered there was a large chunk of it that was extremely rare, so i put it back on for 30 secs

I had marinaded it with dark soy sauce and pepper. Then ate it with asparagus and a large home baked white baguette
