Haha I absolutely love this question! Without doubt 22P pink closely followed by 22S because they are so similar. I just thought about it and this is the order of preference from favourite to least favourite (although I seriously love them all

)
22P light pink
22S light pink
21C rose clair
21S lilac pink
21P bubblegum pink
22S dark pink
22C sakura pink
Pinks I have had before and didn't like:
18S iridescent rectangular mini - too coral and mini size doesn't work for me
14C jumbo - absolutely amazing colour second to 22P, hardware was silver, caviar was very dry and jumbo size isn't versatile in a light colour (too scared of getting it dirty)
19S medium iridescent pink - bought into the hype but I have decided now that I just don't like iridescent bags
Only on this forum we can talk about bag colours in this level of depth!
