Bit Lasso just released Swatch to make it easier to manage the color palettes on the Mac. The app lets you import colors from multiple sources, add colors with Apple’s Color Picker, and by entering color values. You can organize palettes, export colors and palettes, and more. Swatch lives in your menu bar for quick access. The app requires macOS High Sierra or Mojave and is available on Apple’s Mac App Store for US$9.99.
Paul Hayes at Sky & Telescope has written a great tip about how to use the iPhone’s accessibility features to turn the iPhone’s entire display a specific color profile. For example, if you need to shade the iPhone’s entire display permanently reddish in order to preserve night-time dark adaption, you can do that. This technique would be particularly handy for amateur astronomers. While some astronomy apps have this feature, this tip applies to the iPhone’s display across the board. The tip is beautifully described, including an explanation of accessibility shortcuts, and also invites exploration for those who have certain kinds of color blindness. Check it out.
