Instrument Tube Colors

[Romeo Delta]

Is there a standard for pneumatic instrument tubing colors?

Best I can tell in my LS-4:

Green is TE
Red is Pitot
Blue is Static

Does this jive? Is there a standard?

Additionally, there are three preplumbed Cream-colored tubes coming
from the capacity flask storage area.

I have one unused Yellow tube.
Anybody know where that one comes from/goes to?
An alternative static source, perhaps?

And no, I don't have a "you're too damn close to me in this thermal"
pee out of the gear box warning system.

Folk--

Closer perusal of the LS-4 Flight Manual (duh!) finds my color
assumtions were indeed correct. And the Yellow line is to the aft
static source.

Asked and answered--you gotta luv it!
