Cooling fluid

Hi mates.
Since my car is actually 4 years old, due to service manual, cooling fluid should be changed among other stuff. Are there any parameters specified by Renault for it, or does it not matter, which kind/colour/brand will I use? No mention in service manual about this. Actually I have any pink coloured stuff filled in. Any guess, how much of the fluid is needed? Thanks.
 
I've just always used halfords advanced coolant. It's red coloured but I don't know if the colour denote a specific type?
