When seen in babies, the color often shifts to one or the other as it matures and do no qualify as true ‘bacon’ gargoyles. It isn’t as common to see the dual coloration retained in an adult, but adults that do retain both are absolutely stunning. This adult color combination is sometimes referred to as ‘bacon’. Bacon coloration is generally seen with a red dorsal bar, and orange side and lateral bars (if present).
