Ombre vs. Gradient - I got it wrong!?

So apparently all this time what I (and most of the world) have been calling ombre nails have in actual fact been gradient nails.

The Swatchaholic informed me of the error of my ways. 

You may notice I have gone through a lot of my posts and changed my mistake.

 Pretty much,

Ombre nails are where one nail is painted a different solid colour - that goes gradually from lighter to darker.

for example

and gradient nails are where each nail changes gradually between two colours.

For Example

 

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.
