Somehow watching the picture above I've figured it out, you have to match the colors like this
First the right side, from the bottom left to right:
Pilar 1 ( the blue ), Pliar 2 (yellow ), Pillar 3 (green) - press button on each pillar untill it matches the color from the coresponding one from the left room ... Pillar 1 button goes green, Pillar 2 button red, Pillar 3 button yellow.
Same for other pillars then move to the left room and do same.
Picture attached with the colors on each button
