But the fireworks celebrating the home team's victory had barely subsided when the disastrous news of its superstar striker Neymar being ruled out of the tournament was made public.
The 22-year-old superstar striker, who lit up the World Cup with his skill and temperament, fractured a bone in his back (third vertebra) when he was kneed in the back by Colombia defender Juan Camilo Zuniga.
Luiz doubled the Brazilian lead with his spectacular free kick that crashed into the top right of the net in the 69th minute after skipper Thiago Silva's first half strike off a Neymar corner kick had put the hosts ahead.
Colombia pulled one back when James Rodriguez converted a penalty in the 80th minute but the Brazilians held their nerves in the tense remaining minutes to set up a last-four clash with European powerhouse Germany.
In a fast and frenetic quarterfinal clash, Brazil came up with their best show so far in the tournament and Colombia too put up a spirited fight.
Young Colombia striker Rodriguez was gutted as he left the field in tears before exchanging his shirt with Luiz, who consoled the rival player.
Silva struck as early as in the seventh minute when Neymar's corner was missed by Luiz in the middle but the home skipper smashed in with his knee.
