Description

Once #188 is finished, we're going to need to get new shades of the noun-gender annotation colors. These changes will happen in KeyboardsBase/ColorVariables.swift. The light mode colors will need to be made darker, and the dark mode colors will need to be made lighter (light mode annotations were over white, but are now over light grey, and dark mode annotations were over black, but are now over dark grey).

I think the best way to do this is to use the palette tool at coolors.co. If someone wants to do this, then I can show them how it works. We'd just need to put in the current colors, and then use the tool to go one shade lighter or darker. We'll then check how it looks and go from there.

• This issue is blocked by the work that's being done in Alphabetized Autocomplete #188, as the changes to the UI make the color changes necessary

Contribution

I'd be happy to do this if no one has interest :)

@SaurabhJamadagni, all I did here was make the dark mode colors one shade lighter and the light mode colors one shade darker :) Let me know if you think the new versions work 😊
