Red is usually longlife antifreeze, blue is normal mono ethylene glycol or MEG, if blue is in yer bottle then make sure you top up with BS6580 antifreeze but it is quite the norm now been in place since 1992, thats got all yer Anti corrosion inhibitors in, get a cheap hydrometer/antifreeze tester (£4.99 from halfrauds), to check you antifreeze concentration levels, a 50/50 mix will usually protect down to -15 with good antifreeze.

I changed over to OAT six years ago the five year life sold it for me, I replace the coolent again last Novenber so still got four years to go, before that it was Rovers green-yellow stuff and replaced every two years.
I only use 5 litre in my 11.3 litre cooling system thats gives protection beyond -25c according to my hydrometor.

If the P gaskets and water pumps didnt go so often and dump the bloody coolant out it wouldnt hurt so much as the good ones are fit and forget for 2-5 years nowadays....but,if,like me,you end up doing refills 3 times ayear on a minimum of two running discos it hurts.So why is MEG so bloody expensive?Its not a complex chemical after all...????

I blag trade price at Andrew Page's for 5 litres of pink OAT for £11.75 so not too bad, but still not cheap.
Have been through about 25 litres this year so far

Thats very good compaired with Halfords at £22 which I believe is Comma's stuff.
Why don't you drain into a bucket and then reuse, you may spill a drop but easy then just to top-up.
3x a year is too often to be changing the coolant, or for the P gasket or water pump to fail. You have a problem somewhere, either with fitting low quality parts or workshop technique.
If its necessary to drain and refill with coolant, and its been replaced quite frequently, then it would be sensible to capture it during draining and re-use it. If its necessary to test for leaks, a good idea is to fill initially with water, then once you're happy drain the water and refill with coolant. But with good workshop practice, ie making sure gasket sealing surfaces are clean, etc this shouldn't be necessary.

No but the Landie has. I have changed the stat twice, new waterpump, new top hose, new heater hoses, new radiator...all in the last 10 months

I did that, but every time there was an oily film on the top so I did not risk re-using it even after filtering it through a micro-fibre cloth

Oily film-that doesnt sound good
Not as bad as it sounds - It was picking it up off the draglink from the leaking PAS box
