I just wanted to come back and say that I played with it a while and found a fix [more of a workaround really] that you can do to at least record in proper colours for now (until it is fixed properly in an update by NVIDIA/AMD or EA/Maxis), and that is: run the game in Windowed Mode.
I made a quick little post at my blog about it, but here is the evidence that it works - a comparison of stills from two videos recorded in the two different display modes for the game (fullscreen and windowed):
- Comparison between the display modes and the colours when recording (Darker vs. 'Normal') for the recording issue with The Sims 3, showing that the workaround works [at least for now]. In the right half, the camera has been 'zoomed in'

If you want to read the post I made about it at my blog, you can do it here
, but the tip and the still comparison picture used are all right here.
Try it out - I hope it works for you too!
