A wire spool (10) with color identification includes an axial tube (20), a first flange (30) extending from a first end (21) of the axial tube (20), and a second flange (40) extending from a second end (22) of the axial tube (20). The wire spool (10) is characterized in that the first flange (30) has at least one depression (32) coated with a color layer (48). Thus, the color layer (48) is not easy to peel and the cost of manufacturing the wire spool (10) can be reduced.
