The Ninja Turtles stand around their teacher, Splinter, striking a classic pose of respect. Splinter is a rat with a gentle face and long, white beard. He wears a dignified brown robe with a staff in his right hand. Leonardo stands at the front wearing his signature blue. Next to him is Donatello in dark purple, with Raphael in bright red, and Michelangelo in cheerful orange. All four teenage turtles have their swords at their sides, ready to take on any challenge.
To best color this page, consider using bright and bold colors. Splinter's staff could be highlighted with gold or yellow to draw attention to it. Each turtle could have different shades of their respective colors, like muted blues and soft purples for more realism. To add an action-packed scene, Leonardo can be seen leading the group with an intense expression, and the other turtles can have dynamic expressions and postures to highlight their individual personalities. Finally, for more depth and shadow, add natural brown and gray tones to the edges and background.
