Clutch and brake fluid longevity

I changed my brake and clutch fluid at the same time. Already the fluid in my clutch reservoir is yellowy reddish, whereas both brakes are pretty clear still. The same thing happened on my mates ducati.

So does that indicate a problem, or is it just down to differences between the clutch and brake systems?

 

On my old RR6 same thing happened every time, in weeks the clutch fluid had gone dark.

 

yeah it doesnt take long to go dark

 

Wonder why that is?

So long as it's not a problem, I'm happy.... cheers gents.

 

I put it down to heat from engine...
