Adding a "library" of additional eyedroppers

[RBH]

In "Levels" and "Curves", there are 3 eyedroppers for black, white, and gray. Actually, these eyedroppers can be set for any user color by setting the desired levels of the RGB, CMYK, ...etc. choices offered.

I would like to see a user defined larger group of choices, where I could preset the droppers to various type of skin tones, green foliage, blue sky, and whatever I choose to define. I know that I can customize the standard 3 eyedroppers, but I'd like to have these special color droppers available as an extra capability, preferably in their own palette, where I can name them accordingly, and use them when wanted.

I knmow from experiende that setting a grey card to true gray with the standard gey eyedropper is the best approach to getting the right color for an image. I now use a special card with white and Grey and black om it, and out it into images for use later when editing et al.

Having such eyedroppers would make things easier to do when I have an image that does not include my special card.

Does anyone know of a way to do this in Photoshop 7.0.1, or if there are any plugins that can accomplish this?
