Pigment is really fun to use and easy to figure out. I really like the color palates that they provide, because it allows your colors to easily look really nice together. I am also really impressed with the quality and breadth of drawings to color! The different coloring implements also work well, and the color within the lines feature makes my coloring look a lot better than it would in real life. This feature is also handy when coloring in a train or plane, when turbulence might otherwise interrupt you.
The only downside I see is the cost. I liked the app so much that I bought a year subscription after a week with it. At $50, I find this one year fee rather steep. After all, Im not getting any actual materials, just access to some pre made color palates and new sketches. It would also make more sense if I had to pay $50 one time for the app. Im pretty sure that next year I will be frustrated when $50 gets subtracted from my bank account, but I do like the app, and I will keep my subscription.
Im happy to see they keep updating this app with more content and coloring tools!
