Colour select issues

[Emma303408072y74]

Hi, 

I've been having issues with importing footage into After Effects and being over exposed, so I've been poking around in the colour settings. 

But now I have a bigger issue where I do not have full range of colour selection and I'm unsure how to restore it. Please see attached image. 
How do I restore to normal colour functions?

Thanks for your time

It looks like your colour management is set to some kind of Log color space.

Go to File > Project Settings > Color.  The default colour management settings look like the image below.  Unless there's a specific reason, the safe setting for Working Color Space is "None".

 

I have also posted in the other thread you've created.  Might be wise to stick to one thread.
