Dark mode icon hard to parse

This template is for bug report only:

  • Lettera Version: 1.0.0 (4266)

  • macOS Version: 26.6.2

  • What were you doing: using Mac in dark mode

  • What feature did you use: the app icon

  • What happened: difficult to tell what the icon is without close inspection. the dark part of the “A” is very similar in color to the dark icon background, while the light part of the A is very different. So the icon visually reads as just a curve at the top-right of the icon

  • What did you expect to happen: “a” is clearly distinguishable in dark mode, as it is in light mode
