-====== Color Shotgun ======+====== How the Color Shotgun works ======
  
 How the Color Shotgun works is it converts the selected color into a L*a*b color or Lch color then creates a range of colors and converts those to the output color. How the Color Shotgun works is it converts the selected color into a L*a*b color or Lch color then creates a range of colors and converts those to the output color.

-CMYK colors may not be converted to the same color percentage since the starting color is converted from CMYK to a L*a*b color then back to CMYK. This is because the black color value is not preserved, and since there are multiple ways to create same in CMYK, the final color formula is determined by the ICC Color Profile used.+CMYK colors may not be converted to the same color formula on the chart, This is because the starting color is converted from CMYK to a L*a*b color then back to CMYK. and black values are not preserved, and since there are multiple ways to create the same in CMYK, the **output color formula is determined by the ICC Color Profile used.**

 +Secondly, The assumption is that the starting CMYK color is not correct and that the goal is to find a CMYK mix that produces the correct color on a digital printer that matches a sample or colour book. To that end, the actual CMYK mix used is not as important as the colour produced.
  
 //It's important to remember that when printing to a digital printer, the color in your file is not the color formula used to print to the media. If your artwork is CMYK 0,100,50,0% that formula simply tells the printer what color you want. That formula will past through multiple color profiles and correction curves, so the actual mixtures of ink used on the media will be different. It should not be a concern if your starting colour changes from CMYK 0,95,70,25% to something more random CMYK 18,100,81,9% as they both will print the same colour on a digital printer. //  //It's important to remember that when printing to a digital printer, the color in your file is not the color formula used to print to the media.

 +==== Pantone Color Books====
 +
 +PowerScripts can read .acb files such as PANTONE+ Solid Coated.ACB, Until November 2022, these were supplied with Illustrator; however, after 2022, you must provide your Pantone color books.
 +
 +To use Pantone Colors, your options are
 +
 +  * If you have an older version of Adobe Illustrator, you can search in the folders below and copy the files to the latest version of Illustrator.
 +    * Max:  /Applications/Adobe Illustrator XXXX/Presets.localized/en_US/Swatches/Color Books
 +    * Windows: C:\Program Files\Adobe\Adobe Illustrator XXXXPresets\en_US\Swatches\Color Books
 +  * Search for them online, Google "Pantone color libraries acb" and download copies of the color books
 +  * Use the Pantone Extension and get the Lab value for the Pantone and manually enter this in 
 +  * Use a physical color book, and enter in the RGB value (make sure your color settings are set to sRGB) for more accurate starting points
 +
 +**Where to place the .abc files**
 +  * You can install them in in the Color Book folder for Illustrator, see above
 +  * You can click the button in the script and manually open each .abc file.
 +  * You can place them in a custom folder, and in Color Shotgun, go to the [Color] Tab and enter the location of the folder in the "Location of Color Book" setting. Restart the script and it will load the color books.
 +
 +** ASE files **
 +We are adding in support in a future update for ASE files.
