Comment (by KZeni):

 https://github.com/helen/admin-color-schemer creates a copy of the `wp-
 admin/css/colors/_admin.scss` file to generate its custom color schemes
 (it then uses its copy of this file at `wp-content/uploads/admin-color-
 schemer/_admin.scss`.) This is where I encountered this issue (and
 confirmed just now that it is still an issue.) It shows the checked
 checkboxes as broken images instead of displaying the SVG as expected.

 Again, just swapping out `@return '%23' + str-slice( '#{ $color }', 2, -1
 );` to instead be `@return '%23' + str-slice( %23{ $color }, 2, -1 );`
 fixes the issue and doesn't appear to have any side-effects.
