On the Subject of Flashing Circles

Circles are a bizarre choice for this disco mat, to be honest.

The module contains a grid of 36 circles and a red start button along the right.

When the start button is pressed, the circles will all flash different colour sequences, apart from two, which will flash an identical sequence of colours.

This sequence will be 10 flashes long, and the flashes will be one of 6 colours, Red, Green, Blue, Cyan, Magenta, or Yellow.

Select the 2 circles which are flashing the same sequence to solve the module.

You may press the start button as many times as you want without penalty. A strike will be given for an incorrect press but it will not reset the module.
