I do not see where a "laryngal" is needed since I believe the final long
*-a(:) was part of the simple root form.
If we add adjectival -*y to the full form, -*a: + -*y combines to form
*g^hlé:-; if we add the color formant -*w(o) to the full form, -*a: + -*w
combines to form *g^hló:-.

What about the latin word flo:rus "blond"
obviously a cognate of greek khlo:ros ?
I cannot see how a:+w can become o:
in either latin or greek.
