Describe the bug

When I try to set a custom name color, quotation marks are automatically added around the color hex code after saving and the custom name color doesn't work (probably because of the quotation marks).

Reproduction

1. Go to Settings -> Account -> Global Name Color
2. Try to set a color
3. Upon clicking save, for example #00FFFF gets changed to "#00FFFF" and upon clicking in the text box again, it is changed to #"#00FFFF"

Expected behavior

Quotation marks aren't added (I'm assuming that's the problem) and the custom name color works

Platform and versions

OS: Linux
Browser: Firefox 147.0.4
Sable version: 1.2.1 on app.sable.moe
