I'm hoping that's just a sample---we all know UAL grey is a medium-dark grey, not pale. It looks like they used "BAe grey" for the wings AND fuselage, which is totally wrong. It'd be like painting a UA o/c 777 with Boeing grey on the fuselage. It should be pale/BAe grey on the wings like every other 146 out there, but (obviously) UAL grey on the fuselage. See here, the contrast between the pale grey wings and the darker grey fuselage is very obvious:
As is, the model looks almost like the "ghost of UAL" with how pale it is. The wing part of the mold actually needs 2 different greys applied to it----1 color for the wings themselves, then UAL grey in the center/top.
I *really* hope this comes out right in the final production version, as a grey/blue 146 is my most-wanted 146 of all.
::edit:: OK, here's my quick attempt to show how it SHOULD look:
