Astroboy, your pix are always so nice! Clearly conveys your model's character.
As regards the choice of coloration, I feel this must a point of artistry determined by the individual. IF the Falcon were a real thing, then we could get an official paint reference and work from there. As it is, we only can interpret what we see on the small/big screen showing the original VHS or DVD or Blue Ray releases or even using our 'mind's eye' of the apparent color. Given the light tone (white?grey?) of the Falcon, ambient lighting also plays a part (think of the approach to the Cloud City...rather orange. ) From a modeling standpoint, IF you decide you are building a model of the "full size" Falcon, then you have scale effects to worry about as well.
On the other hand, if you wish to be true to the actual filming miniature, then I suspect there is a large amount of research and discussion within this Forum (just a little) about how the model was painted. Clues are found just by looking at the now 40 year original with all the missing parts making visible the layers of different colors (tan? dark grey? black?) Of course, white can yellow and other colors can fade, so caution is required with the method as well.
It never hurts to ask how someone else achieved their result, but I feel one should never completely abdicate their artist determination. It is after all part of the fun (and the risk, though that can be minimized by conducting 'dry runs' and tests before committing...)
Sorry, dropping out of 'philosophic' mode!
