Yeahh I don't know it was the display or what but It did not feel as buttery as the other Velux pearl shades And yes I do agree that it does not have as much sheen as Antiqued. Surprisingly Antiqued and DF looked identical on my skin in terms of color, besides the texture difference, I even tried them in different light settings.
Expensive Pink is darker deeper shade that AL , X - I think is lighter and has very very slight hint of more gold in it than pink, but it is barely noticeable , at least again on my skin.
In terms of Grape pigment and HM - i think grape has the same color sheen as the HM - so when i thought of that it was a skip.
The bright colors like Lucky green, i find using them with Peachy/Orangy/ Brown shades and it looks amazing, or i just use it as an accent color of fun on my lower lash line.
