It's the red line that you should be following on - because the rule of left hand lane for the first and possibly second exit is right, right hand for everything else. It's clearly the third exit off the roundabout so you should use right.

If you're going the opposite way you should be in the lane that you are going into i.e. left if you're going into the left lane beyond the roundabout and right if you're going in the right lane beyond the roundabout. If the roundabout wasn't there you are basically staying in the lane that you need to be in. This applies when the road is the direct continuation of the road you are on (only with a roundabout obstructing it).
