Black and white icons invisible in OS X "Dark Mode"

What steps will reproduce the problem?
1. Enable OSX "Dark Mode" (System Prefs - General - "Use dark menu bar and dock"
2. Enable B&W icons in NoSleep
3. Watch icons disappear

What is the expected output? What do you see instead?
Expected output would be a visible icon. :) Instead, there is a "blank" spot on 
the dark menu bar that responds normally when clicked, but is only visible when 
secondary-clicked.

What version of the product are you using? On what operating system?
NoSleep 1.3.3, OSX Yosemite 10.10

Please provide any additional information below.
A white outlined, transparent "ZZ" icon would be great when NoSleep is 
deactivated, turning white when activated.

I'm having similar issues with lots of apps and add-ons, having to manually 
edit the resource files to make them visible. :(
