Updates based on UX review of popup hint

## Use Case

There is currently a popup that tries to orient the user to the app. But it's not easy to read and is maybe trying to do too much.

## Solution

1. Change the color to #8048F3
2. make it not italic
3. change the content to click to add to gallery.
4. make a new flag that points to the first image in the gallery that says 'click to load in 3d'
