Answer: In a standard set, every club has a different lie angle - short irons are progressively more upright than longer irons. In a set with any color code other than standard (black color code), the lie angle of EVERY club is adjusted to be more upright or flatter, depending on the color code.
The standard lie angles for G5 irons at standard length are:
2: 58.67
3: 59.32
4: 60.02
5: 60.75
6: 61.50
7: 62.28
8: 63.10
9: 63.95
PW: 64.38
UW: 64.38
SW: 64.70
LW: 65.11
PING Color Codes, going from most upright to flattest are:
Maroon
Silver
White
Green
Blue
Black
Red
Orange
Brown
Gold
Each color code is progressively one degree more upright than the NEXT, or one degree flatter than the PREVIOUS as you read the list from top to bottom.
So, if we use an 8-iron as an example:
A Green color code is 2 degrees more upright than standard, or 63.10 + 2 = 65.10 degrees. Since the color code system takes length into consideration, you must also adjust this number for non-standard lengths as follows:
For every 1/2 inch shorter than standard, the lie angle is approximately (~) 3/4 of a degree more upright. Conversely, every 1/2 inch longer means the club is ~3/4 of a degree flatter.
So, if that same Green color code 8-iron was 1/2 inch longer than standard, the actual lie angle would be 65.10 - ~.75 = ~64.35 degrees. The lie angle of the remaining clubs in the set would need to be calculated in a similar manner.
