Tighnari is a young, lean-built man with fair skin, a slightly delicate face, and shoulder-length, straight dark green hair that has deep black roots and lighter green, leaf-like streaks framing the front of his face. His eyes have pale pupils and a distinctive gradient that shifts from warm brown near the upper portion into green, giving them a sharp yet somewhat soft appearance. Sitting atop his head are two enormous, upright, pointed black fox-like ears, with a gold earring on his right ear consisting of three intricately carved dangling leaves, while behind him is a large, exceptionally fluffy tail colored in two shades of deep green. He wears an elaborate forest-inspired outfit centered around a cropped dark-blue hooded top with black drawstrings, yellow edging, and green and red accents, layered over a black high-neck shirt and a longer white tunic. His hoodie has deliberately asymmetrical sleeves, with one sleeve ending around the elbow and the other extending down toward his wrist, while a large yellow flower ornament decorates his right side and a silver badge with a green tassel sits on the left. His waist is wrapped with a wide purple belt and numerous blue, purple, and multicolored cords, charms, and accessories, with a prominent purple pouch attached at his side. His hands are covered by dark gloves and cuffs decorated with warm gold and orange details, and his lower half is dressed in dark blue pants and sturdy dark boots accented with lighter colors and decorative trim. A long, layered piece of patterned white fabric and additional leaf-like and ornamental panels extend from his upper body and back, giving his silhouette a distinctly botanical, ranger-like appearance. Overall, his design combines deep forest greens and blues with touches of yellow, purple, red, white, and gold, deliberately incorporating flowers, leaves, natural motifs, and layered fabrics into his Forest Watcher attire.
