Blending Brush, Color Wheel
A couple of ideas for premium users:
1. A blending pencil, that smudges colours together if you want to,
2. A colour wheel, as well as the pallets, the pallets are great and i love them, but it is very hard to get the perfect colour.
3. After colouring a book, can the back button go back to where you got the page from, ie the book or the month in the daily section, some people like to colour in multiple images from a book and having to find that page or book is stressful.
4. With the daily pages, can we have a small calendar in the app, like a list of months, so we can go through the daily pictures and colour them all in!
Please add another way to pick colours that would have them all in one place as opposed to us having to scroll through 20 palettes looking for a colour to use. If you could add it for even the paying members that would be great. I've seen several apps with very simple colour wheels along side a tonal slider like the one you have already. A saturation slider would be nice too.
