Question: I'm in the process of doing some usability testing this week for one our iOS apps. We're having them attempt a few targeted tasks to test goals like

* New users should be able to signup with their email in under 15 seconds
* Users should use all their 'votes' inside a challenge
* Users should be able to located 'John Doe', and add him as a friend

We capture the objective results of the task... yes, the user signed up in 9 seconds. But we try to record more subjective things like "the user looked confused on the settings screen."

I'm struggling to find a clear way to organize all the data we're collecting to make it easier to synthesize. 

**What are the best ways to record and organize different kinds of data you get from a usability test session?**

Answer: 
The 'flat design' aesthetic tends to favor large blocks of solid colors. If all of your colors are 'highlighter-esque' then you just end up with an incredibly busy UI where nothing stands out as they are all competing equally for your attention.

Intense vibrant colors--in UI design, at least--are there to draw attention so should only be used sparingly...just as you would with a true highlighter. 

Else, you end up with a hot dog stand:

The answer doesn't depend on wether its flat or 3D because bright "highlighteresque" colors are harsh to the eyes, hard to read, and don't comply with usability guidelines for people with color blindness et. al. As an accent color they are fine but large swaths wouldn't be advisable nor would it be advised to place text on top of that sort of interface. As always context is everything but in light of the question. Not advised.
