Plasma Plays in 21 Ways: "7. Do a Gradient of 2 Colors or More"

I've never done a gradient, although I've seen some on YouTube.  I've tried sponging before, and I didn't like it because it seems as though the sponge soaks up all the polish, and I have to tap forever to get any results.  Not worth it.

So, I figured I'll try it again.  I watched videos, and I was all ready to try my gradient.  But then I noticed that "gradient" and "ombre" were sometimes used interchangeably in a lot of the videos.  And "gradient nails" and "ombre nails" look suspiciously similar.  Hmmm...Well #10 on Plasma Plays in 21 Ways, it says "Ombre Nails".  So what's the difference? 

I couldn't figure it out.  So, I'm going with "gradient=same shades" & "ombre=different colors".  So here are my nails:

Cult Nails "Sandbourne" & "Tulum", tipped with Sinful Colors "This Is It".  I know the gold doesn't look like it's part of the same shade, but it is!  "Sanbourne" & "Tulum" have golden shimmers in them! 

I still don't like this method.  My tips took FOREVER to dry, even with Seche Vite...I guess that's because there were at least 8 layers of polish there!  And they still got a little ruined cuz I had to use the restroom when they weren't completely set!  Ugh!!!!

So, if you know the difference between gradient & ombre, please share!!!
