HTML Color Chart

A number of people that sit around me need to see several colors on web pages at the same time to see which ones look best next to each other. And because every monitor affects the color in its own special way, a generated chart seemed to work best. This quick and dirty macro did exactly what we needed and only took 30 minutes to write (then I tweaked and made pretty for a couple days!). After I was all finished they said, “but how can I tell how it looks against my colored backgrounds?” See the chooser box on the right generated by the ‘ChoosertheSecond’ module.

This example displays the use of an array (ColChoice and DecChoice), and three nested For...Next statements, UBound and LBound. And a bunch of crazy stuff in HTML.

Public Input_Dir As String

Since I did the original 256 color chart in 2000, new browsers can handle an almost infinite number of colors. The chart was expanded to 1,331 colors by adding several more choices to the arrays.
