suit color

Stick with black.

Mine is black and blue with a little white on the back.  It was the only color available, or I would have chosen something lighter for AZ.  Not sure it matters much at 110, though.   Most important is that it is colors you like.  The dark is more common, but as long as I'm in spandex, I may as well stand out.  My next set will be multi-color or flourescent - or Auburn colors (I'm an Auburn Grad.). 

To answer, I noticed the dark colors in direct sun, but after two sessions I got used to it.

^^ You are wise beyond your years!! 

rule of thumb:

black=hot

white=clear

red=fast

Black if you want the....'coverage'

yup.  I went with the white/blue for that very reason.

Cooler is faster.

White tends to be see-thru when wet (so it's fine for some panels and not others).

Many top trisuits use ColdBlack or other technologies where the suit absorbs the visible light spectrum (i.e. looks black), but reflects IR (heat) wavelengths.  The result is a black suit that is as cool as a white suit.  Doesn't look like the 2XU suits have this (looking at their site).

Seriously, some of that has to be photoshopped.  You'd think somebody would have said something.  That's just nasty looking.  

2XU does utilize this technology but not in every suit.  This type of tech is found "Dark Shield" and "Ice X" fabrics.  I inquired about the difference and this what 2XU said...the Dark Shield basically just reflects infrared heat rays, while the Ice-X reflects infrared heat rays and draws heat from the body out having the ability to cool the skin by up to 5.4 degrees F.

We (Rocket Science Sports) did a lab study of different suit materials and found that white reduces sweat loss and heart rate over black materials. Even Cold Black and other technologies are going to be hotter than a comparable white material. Even white cotton was cooler than a leading black material over 1 hour of exertion (under a heat lamp, on a trainer). 

As for white being see through, we line the inside of our white suits with a dark lining to protect privacy. 

And yes, white does show splashed beverages, spilled goo, etc more than black, but hey YOU ARE RACING :-) You'll have kick azz finisher pics and it all comes out in the wash.
