Gru stands before three mischievous minions, all donning blue overalls and sporting a single eye each. His stern expression doesn't seem to phase the playful trio, holding hands and grinning away with childish glee. Color Gru's turtleneck and pants a dark black. The minions' faces can be a lighter shade of yellow, while their overalls should be painted a bright blue. The eye of each minion can be a unique color, with pink, purple, and green being particularly delightful choices. Together, the hues will bring these characters to life, creating a coloring page filled with exciting and charming possibilities.
