To solve this puzzle you have to memorize the color of the lights flashing on top of the columns. Once you activate the device, it'll flash red and blue lights in random sequence above the columns and in the end all four columns will flash with the same color. That's the color, order of which you have to repeat.

To make things easier just choose any color (red or blue), activate the device and type the order of the columns into the chat window, while the columns are flashing. If in the end different color will flash on all four columns, just repeat this again until needed color will be that same as you've been tracking.

One more note, there is a time limit under which you have to activate the columns. So be quick about it.
If you're doing it correctly the column will flash yellow. If you've mistaken or doing it slowly the column will flash red.
