In the interests of science I just tried it out. The verdict- it is even better than I thought.
It tells you to take a picture. Then you tap "Use".
It then goes back to the app. And you just move your finger around the picture to get the colours. So if I am pointing at the brown pot I get the matching brown colour and shades of brown close to it.
But if you tap at the top on Harmony instead of Strip it gives you the matching colour and co-ordinating colours.
Then if you point to the plant it gives you the matching green colour.
You get the idea.
The best bit is it seems really quite accurate.
Oh I love a new toy, especially when it is free.
We must thank hbfotografic who showed this to me.
Maree are you waiting to get your phone as a present?
