History
Colo High School was established in 1978 in demountable buildings at North Richmond. The current permanent site was occupied in 1980. The blue and white colours were chosen to match colours selected by the Uniform Committee. Sam Weller, the school's first Deputy Principal, suggested using the school building plan as a basis for the logo. David Stone, founding Mathematics teacher, drew up the design which was accepted as the school badge. The shape also represents the Tree Of Knowledge, and its three sections, Students, Staff and the Community.
