ColourEQ is described as the first "super-parametric" equalizer. It uses a higher-order filtering scheme which leads to a qualitatively and quantitatively new frequency response. The additional degrees of freedom introduced lead to four controls per band instead of the traditional three as in standard parametric EQs.

Further features:

• Internal 64 bit processing.
• Free choice of colour palette in the GUI.
• Resizable plugin window.
• Curve display with auto-scaling.
• Coded in proprietary C++, low CPU usage.
