Here are Zoya Suri and Sinful Colors I Love You:
Zoya's words) "medium blue-toned purple with delicate red and blue shimmer and a smooth metallic finish." I Love You is definitely not "Barney purple" (Barney himself is definitely a more red-toned purple) but like Suri is more of a royal purple. ILU is much more glittery, of course. Scrangie says it has a jelly base, which I did not remember. Scrangie likes it a lot, in fact. So do I, although I rarely remember to wear it. Since it's a jelly, it either needs an undercoat or a lot of coats - I think the latter is the way I used to wear it. I'm not sure if the line you can see there is the actual fill line but I think that's approximately how much of it I've used - quite a lot.
Suri is a current Zoya color; I Love You is apparently not in Sinful's current lineup - that link should go to the polish that is most obviously similar, although it's from the Sinful Shine lineup so it's almost certainly not exactly the same.
