In this case it means 'matching'. The color of the pleated patent leather matches the color of the suedeHi,
does anyone know what 'a tono' means in a fashion context. Describing bags for example:Ante coordinado con charol arrugado a tono con asa en pavonado
Suede (bag) matched with toned wrinkled patent leather with blued handle.
it's completely a guess though...any ideas?
