Background color in navbar is gone in 7.1 and 7.2

[lakromani]

I do like to color the navbar to differentiate the apps. It makes it easy for the user to see on the bar what apps they are inn.
But on 7.1/7.2 this is gone due to the new design.

I add this
default/data/ui/nav/default.xml
nav color="#6699ff"

to get nice color.

Anyone know how to get back the color in 7.1/7.2 as it was in 7.0

UPDATE (still missing in 7.2)
You can use the information from alacercogitatus post and modify every dashboard, but if you have a default.xml like this:

<nav">
  <collection label="Views">
    <view name="my app#1" default='true'/>
    <view name="my app#2"/>
    <view name="my app#3"/>
  </collection>
  <view name="search"/>
  <view name="reports"/>
  <view name="alerts"/>
  <view name="dashboards"/>
</nav>

You only change color for my app#1 to my app#3
When you select search, reports, alerts and dashboard it goes back to default splunk color for the nav bar.

I the old way with nav color, color stayed on for all menu item....

<nav color="#d15c34"">
  <collection label="Views">
    <view name="my app#1" default='true'/>
    <view name="my app#2"/>
    <view name="my app#3"/>
  </collection>
  <view name="search"/>
  <view name="reports"/>
  <view name="alerts"/>
  <view name="dashboards"/>
</nav>
