More colors to assign to teachers! Merged

Please provide more colors to assign to teachers. DSP only offers 16 colors but we have 23 teachers on staff (this does not include guest teachers, choreographers, etc - just our day to day staff). Sixteen hardly seems like enough colors to address the needs of most studios, right? Are we that unusual? We need at least 24 (we can recycle the same color for guest teachers, etc.). This would make reading the appointment calendar much easier. A gradient color wheel would be the best option but at least a palette with 24 colors or more.
