American traditional, Western traditional or simply traditional is a tattoo style featuring bold black outlines and a limited color palette, with common motifs influenced by sailor tattoos. The style is sometimes called old school

A "neo traditional tattoo" is a modern take on classic American traditional tattoos, incorporating the bold lines and vibrant colors of the traditional style while adding more intricate details, shading, and sometimes elements from other art styles to create a more dynamic and visually complex design, essentially updating the traditional aesthetic with a contemporary flair.
