Wanted to post this with my pics of YT but I'm still waiting for it...
But as LH colors are a repeat discussion particularly around YT, here's some info about LH's (classic) colors some may not know:
Lufthansa's livery changes did NOT go hand in hand with color changes. LH's major livery changes occured in 1967/68 (introduction of the "disc" on tail) and 1988/89 (no cheatline)
The colors - among a few other details - however changed in 1962 and again in 1979. The next change was as late as 2018.
Consequently, early delivery 747s had different colors than 1980's delivered airframes. The latter had identical colors to the later post-1988 livery. Just in case you wonder why there's no visible color difference in pics around year 1990, yet the retro-748 has different colors.
YT was painted to resemble 747 colors "as delivered" around 1970.
Until 2018, LH used colors within the RAL system.
1962 to 1979, this was blue RAL5013 and yellow RAL1003.
1979 to 2017, blue RAL5022 and yellow RAL1028 was used.
Here's a look at an LH 747 in 1970's livery (this is what YT resembles - well, at least to some degree)

And in contrast: 1982 delivered YX - near impossible to tell the different colors apart, but the smaller titles give "1980's" away.

Here's some tail's in 1988-2017 colors with YT inbetween. See the different colors?
Finally, I quickly made up some LH artwork (a 1980's crane) using the corresponding RAL web-color to visualize the difference.
Left is RAL1003/5013 as used between 1962 and 1979
Right is RAL1028/5022 as used between 1979 and 2017.
