Based on temptalia and others’ swatches, I reckon I got a dud bottle of Force (however, a dud bottle of Illamasqua is still decent by other brands’ standards). Whenever I put top coat on mine, it darkens the colour in patches and leaves drag marks. I know, I know, it sounds like “you’re just putting top coat on too early, fool” but one time I tested this by putting top coat on several hours after painting my nails and I still had this issue. Oh well. I might repurchase if I see it on sale, coz even with this issue, it’s still very long-wearing and pigmented.
Illamasqua Nail Varnish Force ($14.00 for 0.50 fl. oz.) is described as a “deep electric blue.” It’s a really rich, cornflower blue with a creamy finish, and it even has a faint purpleness to it. It almost looks purple in certain lighting–more royal blue than electric blue to me! Deborah Lippmann I Know What Boys Like is similar but bluer. Essie Declare Your Denim is a bit darker and bluer.
