on this topic, i will try to relate the facts as stated by beren, I think, re; colours @ night. Anything other than white is bad for collecting dew. Something about ir reflectivity or ? . There's a thread in here somewhere.
ptn, 2 x 10'' dobs, no more than 8 ft apart, mine = white, his = red. Results = mine dry, his was dripping.
Now I totally agree with what's been said re; daytime, but do you normally view then?
fwiw, it's a personal choice. All depends if you want a dry tube or a wet 1 in the car.
Been said, but they are easier to see @ night.

ps. that's 1500 for me.Yaa!
