PHP Color normalizer

Normalize HTML colors.

On websites, we often need to manipulate the colours we get in different ways. For example, from the user or from another application layer.

This package provides a simple way to normalize the received color to a canonical shape.

When normalizing, you can choose to convert to short or long notation:

Examples:

Color::normalize('#aaA'); // '#aaa'
Color::normalize('#abcd'); // '#abc'
Color::normalize('#aaAAaa'); // '#aaa'
Color::normalize('#aaA', Color::FORMAT_LONG); // '#aaaaaa'

A second parameter can be used for formatting, which has possible values:

• Color::FORMAT_SHORT prefers short notation (if possible)
• Color::FORMAT_LONG always returns a long notation
