First things first: Though this update does give you several color palettes to choose from--including, thank goodness, several shades of skin tone--you'll need to pay an additional $2 if you want unlimited color choice. Along with the various brushes you can purchase, this brings the total cost for Paper to $9, which I think is more than fair for what the app can do.

And what a color tool Paper has brought forth. Mixer is both a color picker and a palette mixer: You can either tap the white circle inside the Mixer to bring up sliders that allow you to pick the right color shade, or you can rely on old-school color mixing to get what you want. Pick an initial color from the palette view and swirl the white circle clockwise until the color takes up the entirety of the black circle, then pick a secondary color and swirl the white circle counter clockwise (as if you were mixing it into the circle). Your initial color will change into the second color, giving you all the hues in-between to pick from. You can even go back and forth--clockwise and counter-clockwise--to see the full range between colors.

Much like the app's other features, the Mixer takes a few moments to get used to, but once you do, it's unbelievably cool and very useful. And once you find a color that you like, you can either draw with it directly, or save the color as a permanent shade. Paper gives you two empty palette sheets for storing custom colors; you can also overwrite system colors by dropping new color samples on top of them. (To restore the app's original colors, tap on the FiftyThree logo in the upper right corner of the notebook screen, then tap Tools.)

The other big addition in this update is support for the Pogo Connect, a review unit of which I happened to have on hand. Working with the Pogo's pressure support is a dream: It's well-balanced, and the software implementation in Paper is simple and easy to set up. If you have a Connect, go to the FiftyThree logo and tap on Pogo Connect, then flip the toggle to On; the app finds the Pogo, then displays its status, battery level, firmware, and an option for toggling the Pen button to use Undo.

Actual usage of that pressure sensitivity in Paper varies depending on the tool you're using. The Draw (fountain pen), Outline (marker), and Color (watercolor brush) tools translate pressure to line-width: They start off thin, then increase about three times in size. The Sketch (pencil) and Write (felt pen) tools, in contrast, don't seem to take any pressure input at all.
