After replying to Ann’s comment, I realise that I have one more peach blush to compare HK F&G with. That is MAC’s Dainty Mineralize Blush.
So I took some photos again and lo and behold, it looks to be that HK is not similar to any of the 3 other peach blushes I own.

Upon closer inspection, you can see that Dainty is even closer to NARS Orgasm than Hipness (Hipness is ‘rouge-ier’)

Now, these 3 definitely belong to a group. NARS Orgasm will have the highest level of iridescence, followed by MAC Dainty then Fafi’s Hipness will be the most matte blush of the 3.
