That 71 sure looks like the same color as 70 Competition Green but it could have been repainted and again, it's on a computer monitor. dfwcatsclub, do you have any information to back up your statement that the 70 & 71 colors are NOT the same?
Only seen it in person and have PPG color charts...
It's different. It is the same code but you would never confuse them in person. One is as you know it -- the 70 Comp Green -- the other is quite metallic looking.
Do some Google searches for "Grabber Green Metallic" to see if there are some pics online. I have regular pics -- no digital.
I thought there were some good PPG paint chips online that clearly discern. The scans provided are very poor.
