I've been using 3-digit hex color values in CSS for a long time: #fff
, #999
, #069
, etc. I can see how the repeating letters/numbers are merged to create a 3-digit hex color code, but I don't fully understand the pattern to be able to write a converter in PHP. Is there documentation for this?
Edit: Oh, perhaps my question wasn't clear. I need to know how some of the 6-digit hex color values are converted to 3-digits. xxxxxx
(ffffff
) and xxyyzz
(006699
) – these are the only two patterns, correct?
