I suppose if we go back to Channel Airways they adopted this process throughout, as their various different secondhand fleets just carried on with the scheme they came with.
Despite the "Golden Jets" based on Continental (they also pinched aspects of Continental's then-current jet types for these new aircraft), when they bought the five ex-Olympic Comets they just carried on as received, no gold anywhere, just bits of the old livery and logo obviously painted out in not-quite-matching blobs of blue and white, giving a decidedly rough appearance.
