 {{{sanitize_hex_color()}}}, {{{sanitize_hex_color_no_hash()}}}, and
 {{{maybe_hash_hex_color()}}} are excellent functions for sanitizing color
 values. Unfortunately, they are defined in wp-includes/class-wp-customize-
 manager.php which is only included when the customizer is initialized. I
 recommend that the functions be moved to wp-includes/formatting.php, where
 other similar functions are located, so that they can be used everywhere
 in WordPress.

 As an example, if you use a color input for adding a color option in a
 theme or plugin, you should be properly sanitizing/escaping the value when
 output in the HTML. Having these three functions available makes this
 process easy and consistent. Additionally, it provides a level of
 consistency between projects as different developers will be using the
 same function for sanitizing data.
