Just follow the instructions. Print 2mm in white, pause and change to red, resume printing 1mm (red), pause and change to black, resume and finish the printing. When its done you will notice how it works.

If you want a explaniation, first you will print with the white filament ( 2mm), you will pause and you have to hange to red and continue. The printer will print the red background of the warning advertisment and the first layers of the "black letters" ( it will be red, obviously). then, you will change the filament to black and the printer will make the rest of the layers of the letters but in black, so there willbe a few layers of the letters ( not the warning advertisment) printed with red filament but then it will be black since you change the filament and the printer will continue printing the rest of the layers of the letters.
