If you want to level a red technique you need red briogh points. Green briogh for green technique and so on. You get red briogh points for leveling, green for clearing dungeons and blue for repeatable quests. Fill the progress bar of your technique with those points and advance it. To advance it you will need briogh crystals of respective color. Crystals come from tech reward chests. Hard techs drop virtuous briogh crystals. You will need those for later levels but virtuous crystals can also be fragmented into the smaller ones using alchemy. Alternative you can just buy the crystals from auction house.
