Question on Latin galbinus

Hello,

Could you help me with the etymology of Latin galbinus "greenish-
yellow". It should be a loan from a centum language based on the
correspondance : PIE *g'h- > XLang. *g- (Germanic? or Celtic?)

The inherited Latin word from the root *g'Helh3- 'yelow-greenish' is
Latin helvus (PIE *g'H-/gH- > Latin *h- )

Thanks,
Marius


P>S>

To explain from where my question:

Latin galbinus is the source of Romanian galben <-> Albanian gjelbër
and my intention is to can trace also the etymology of the Latin
words present in today Romanian too.

What is strange also here, is that even in PAlb, the PIE *g'Hlh3-
will give PAlb *gál- (for PIE *l.h3/*r.h3> PAlb *ar/*al see also PIE
*prh3-wo > Alb *parë 'first')

Derivation:
PIE *g'Hlh3- > [g'/l > g/l] > Early-PAlb *gHlh3- [l.h3 > al~la] >
PAlb *gál-

However because I doubt that the source of Latin galbinus was a PAlb
*gal-b-ina < PIE *g'Hlh3-bh-ino, from here my question regarding a
right source.

Thanks again for any help.
Marius
