Answer
The outline of tughra and the colors used presents the meaning enclosed in a specific tughra.
Step-by-step explanation
Arabic art is full of naturalistic plant inspired imagery. For example, The turgha that bears the meaning, ‘enclosed garden’ has a blue line thinly outlined with gold. If it is observed keenly, there is presence of three swirls of blue and gold floral patterns in the main teardrop. When closely examined, blue flowers are in strings swirled with gold ink leaves painted in alternate positions. This might be taken to mean that the garden of God is surrounded by protective layouts of Sultan Suleyman.
