You say that they should be the correct colour that the model were(even though the photography process bleaches out the light blue colouring anyway). does that include everything then? If that's what i should do then i guess i have some more colour work to do on a certain ship then:

You know, that actually looks pretty good! I know you want the blue because it stands out, but regardless I think either way works perfectly fine. I think bottom line make it blue-grey - the electric blue look is what I would stay away from.

PS: regardless of the end color, have you thought of making the entire row of side lights blue? That orange at the end kinda stands out in a wierd way.
