I’m working on a bright, more monochromatic look and trying to figure out which parameters change the following elements (outlined in various colors):
 
Light green: the background over which the control bar modules sit
Orange, ProChannel effect header: I want to make this black
Red, sends lettering: Can the text be white?
Purple, FX sliders: Can the text colors be changed? I want the sliders to be black, but then the text needs to be white.
Dark blue: I want to be able to change the Event Draw Duration to black-on-white.
 

 
Can anyone help? Oh, and just for grins, here's what I have so far for the Control Bar.
 

 
Here's a shot of the screen. I made a few tweaks to the graphic elements - for example, making the T, L, and O bigger on the automation write buttons. Also, I made Mono interleave and Phase Reverse red so I could parse them easily when scanning console view.
 

I hope you get the help, because I really dig what you've got so far!

Interesting. Might I suggest the theme name "Planet Hoth" when it's done?
 
Totally has the ESB icebase/battle feel to it.
 
:-)

Please tell me you're gonna share this when you're done. :-D
 
Someone help this man out! 

"Dark blue: I want to be able to change the Event Draw Duration to black-on-white."
 
The font is shared with the Track view weirdly. It's called "Focused Track Text", with 'Menu Button" listed under Control Bar

"Orange, ProChannel effect header: I want to make this black"
It's the same colours as console channels. "Unfocused strip background" and when you click on it, "Focused Track Background"

Red, sends lettering: Can the text be white?
 

The color for Sends is in Theme Editor: Global>Horizontal Sliders.
 
But it's also the color for - surprise - the Horizontal Sliders in Track View. 
 

The only one I am not sure can be changed is Light Green.
 
The easiest way I have found to locate items is pull up Tungsten in the Theme Editor, click the view tab and set the filter for modified. Then open your working theme in another instance and apply the same filter. This lets you see what you have not modified which was modified in Tungsten.
 
For example dark blue are a series of images in Control Bar > Modules > Snap which need the 4 image altered. I was looking at snap settings and not Tools Module.
 

I've modified the background colors to a distinct purple. There aren't so many blacks for me to look through. I think the black background is fixed on the Control bar
