I've picked a couple of colors for use in tables, boxes etc. The color function for table backgrounds doesn't seem to remember the colors used throughout the site in its array of "colors in this document" or the like.
Is there a way that I can always have available my selected colors without having to enter its code into the color picker?
Enter them once and put into the custom color pallette for use throughout the site. With each new color scheme you will have to add to it of course - but adding once per web isn't that bad.
