In Advanced coloring mode, you can mimic true coloring experience as if you’re coloring with the real pencil/brush with the real gestures.
In order to enter the Advanced coloring mode, tap on the “Bucket” button located to the left of the active coloring palette.
When you choose "Advanced coloring" mode, you will notice a menu pop up at the bottom part of the screen, where you can pick different kinds of brushes (some are the VIP brushes).
You can also edit the size and opacity of the chosen brush.
Select the “Bucket” button (1st in a row) to go back to “Tap to fill” Basic mode.
By default, we have "Color inside the lines" mode turned on. With this mode turned on, you won't be able to color outside the specific lines (areas).
This can be turned on and off easily by tapping on the special button located in the right lower corner of the coloring.
Please note that this button is only seen when you choose the Advanced Mode.
