My two cents worth.
The problem I have always had with this aircraft and its profiles is they don't match the plane in the layout and potentially all the light blue in every location.
So starting off profiles they nearly all look like this with all the blue bits with its last paint scheme.
Some of the profiles have the text no place near the blue topped nose. Yet every photo has numerous letters on both sides over lapping this blue topped nose. This profile brings the text right to the lines edge yet wont cross it.
So why do most profiles ignore this? The photos below clearly show it overlapping yet they would have us believe its all the same colour blue.
So is it a blue topped nose or is it a standard anti glare panel? Or maybe the text is just another colour other than light blue? There is clearly two colours in play with the text to begin with.
Also here is a couple of real colour photos from the same group with some light blue bits.
They may have different shades of blue a bouts within the group these two would be at least a good base line I think.
So early scheme to the finished all blue like the profile above.
So what colour is the #194? Not like the text & not like the blue anti glare panel on the nose if it is blue.
Now we have partially painted spinners.
Also in this image the air intakes are painted now.
Finally the finished product the wing fillets are now painted as well & #194 seems to be a few shades lighter as well & overall the light blue seems feasible
except for the names text it has to have additional shading around the tops of the letters so not to clash with the blue nose top because they still overlap..
I think there is numerous schemes on this plane depending on what time frame the photos were taken.
