On some models, this is supposed to be depected by magenta, not on the radars I operate though.
And remember that these radars regardless of their age are showing the
rain which is mainly in the cold downdrafts. Warm updrafts will show a lot weaker on the radar but the turbulence will be as bad as the rainy downdraft and sudden changes in OAT can confuse the ADIRUs.
