Purple Nail Polish on Fair Skin
Fair skin sits right in the middle of most nudes and blushes, so warm-versus-cool matters more here than on any other tone. A cool pink and a warm one look like two different colors on you.
Start with Deep violet glitter (RCW38) — cool, near-black violet, and it stands well clear of your skin. 27 of the 29 will read as a real contrast on your hand. If you’d rather go lighter, Soft violet crème (BP67) is more of a lilac.
Change the nail shape and length as you go — the same purple is a different manicure short and round than it is long and stiletto.
The same purples on another skin tone: Pale skin · Olive skin · Tan skin · Brown skin · Dark skin
Or start wider: all purple shades · every color on fair skin
