So apparently all this time what I (and most of the world) have been calling ombre nails have in actual fact been gradient nails.
You may notice I have gone through a lot of my posts and changed my mistake.
Ombre nails are where one nail is painted a different solid colour - that goes gradually from lighter to darker.
and gradient nails are where each nail changes gradually between two colours.
hopefully that clears a few things up, and I now realize I've been labeling a lot of posts wrong, however since everyone seems to get the two confused I think I will still use Ombre when labeling my gradient nail posts.
