Choosing colour of travel awning- and why

[jayjay]

We are about to get a travel awning for short stops added to our Trackie CT.
The canvas of the main tent is predominantly grey, with royal blue trim.  We have to choose either the grey or the blue for the awning.
Just wanting to draw on the wealth of experience on here, as to which way we should jump- in that are there any practical considerations that should impact our decision? eg- does the darker colour make it cooler in summer...... or does it draw the heat? Or any other factors that we should be thinking of?
Thanks

How is the travel awning different to the normal awning?

Ours is a rear-fold, therefore the awning goes the entire lengthof the trailer (as opposed to across the back width)- hence the amount of canvas to put up for a quick stop is rather daunting and cumbersome. A travel awning just zips up one pitch - and is enough to cover the kitchen...... and is only half the canvas.... much quicker.
