Actually Eusebio Tamagnini claimed in his reports based on multiple sources (not just the scaled data of 11,601 adults from across Portgual which were only 2.07% true blond versus light brown) that about 11% of Portuguese adults had true blond hair excluding light brownish shades (
https://www.tapatalk.com/groups/ethn...-t65.html#p263). This is obviously ludicrous because that would make Portuguese at the level of some Central Europeans in blondism (based on Fischer #9-26 8.5% of adults from Volhynia under Pöch and 16.5% of Alsatian adults under Pfitzner were found blond). Southern European anthropological observers can't really automatically be trusted to conduct surveys on their populations due to often significantly different perspectives on the delineation of light features. Most pigmentation scales are of German origin and none are of Southern European origin. Southern Europe was essentially on the anthropological periphery during the late 19th to early 20th centuries so unless German standards are imposed through standard scales extra scrutiny must be applied.
Regarding Fischer #8 this is what was written about Fischer's determination:

The ultimate determination was "fast dunkelblond" or near dark blond. If Swedes are unwilling to come to some agreement regarding a specific shade being at least fairish or råttfärgat it can't fairly be considered blondish universally. #9-26 corresponds to what is at least råttfärgat in Sweden.
Regarding the 2012 GWAS pigmentation study many Southern Italians attend Sapienza University of Rome so the results are not necessarily representative for native Lazians. Clear genetic outliers were excluded (one Irish with Russian ancestry, and two Portuguese with Indian and African ancestry) but that does not mean there was no variation due to regional origin. If you look at the box plots there were quite a few outlier cases in the Italian sample with much lighter hair pigmentation than median which could be indicative of regional variation. There is no reason to indicate this to have been as much a factor for students at the University of Porto.

All this understood at least Northern Italy could likely be blonder than Portuguese on average considering the Lazio study finding 2.36% Fischer-Saller A-L in adults at least as light a range as Fischer #9-26.
