CSS3 color expressions
PCRE (PHP <7.3)
Up to spec as of 2016-03-16. You can choose whether to enforce industry-standard casing for keywords via the "i" flag, which is enabled by default. Note that both "currentcolor" and "currentColor" are common; the relevant spec uses "currentColor", but several browsers prefer "currentcolor".
