Find the closest mathematical color match from a user defined swatch library

[propixelartist541]

I know I'm not the only designer who needs to be able to find the closest match to my artwork in an user defined / created color swatch library.

I would LOVE it if we could either:

1) Gain the ability to create color books using established swatches.  My vendors send me swatch books in .ase or .aco format.  I NEED to find the mathematical closest match within the available swatches in my vendor libraries.

OR

2) Add a "find closest match" function that pulls from a user defined selection of swatches.  

To really make designers happy, this functionality should work in Photoshop, Illustrator, and InDesign at minimum.  It would also be nice if we had the option to see the top 3-5 closest matches.

I am in complete agreement. This is a must-have feature for any print or textile designer. We also work using pre-defined color palettes and often scan in prints and need to find the closest match from within either our own pre-defined color palettes or Pantone library. 

They had a tool that sort of did this in their Textile Designer Beta that I took part in, but have not heard anything since.

Please invite some of your peers to vote and elaborate on your current struggles without that function.
