I could do this, but I'm kinda lazy feeling, and I have this feeling that someone more comfortable with regex could do it easier and faster and better than I.

Here's the scenario: There's a website form where a user enters four colors in hex (with or without the # and with or without capital letters)

Those colors get the # stripped off and are divided into three two character strings apiece.

convert them to decimal.

Then follow a certain pattern to add the strings together and divide by two (essentially creating "inbetween" colors)

then this would be output to the page in a nice table.

Mostly it's just the regex I don't want to do. I'm comfortable with tables and forms and stuff, but things like preg_replace give me the willies.

anyone interested to be my slave for the day?
