# Why is color screening in Quark Gluon Plasma not effective for light quarks mesons like pions?

The color screening of quarkonia states like $$J/\psi$$ (bound states of charm and anti-charm) and $$\Upsilon$$ (bound states of beauty and anti-beauty) is considered one signal of QGP (quark-gluon plasma) formation. This signal is actively measured by experiments at LHC and RHIC.
Why don't we measure the screening on the bound states of light quarks like pions?
