__NOTOC__
{{header| Miscellaneous Variables|ro|Holds the color of the last pixel saved using [[savePix]]. The colors returned by #pixCol are in the format $BBGGRR (where BB <nowiki>=</nowiki> hex value of blue color channel, GG <nowiki>=</nowiki> hex value of green color channel, RR <nowiki>=</nowiki> hex value of red channel). All colors rendered on the screen are created from these 3 primary colors. Each color ranges from 0 (darkest) to 255 (brightest) -- or $00 to $FF.}}

{{Note|
*The client window '''must''' be unobscured by other windows in order for savePix and #pixColor to work.
* #pixCol values differ slightly from computer to computer.
*Most of the content of this page is shamelessly ripped off from a post that Cedryk made in the CC forum. Thanks for the knowledge Cedryk! --[[User:Kedrick Valorite|Kedrick Valorite]] }}
