UPDATED DOWNLOAD LINK

I updated the link for the Excel spreadsheet of ACI to RGB color conversions as I edited my previous post.  I am sorry that my previous link did not work for so long. The link in this post and my previous post should now work.

Just click the download button on the top left corner after opening this link.  I hope this helps you all out!  Please post and let me know that it is working for you.  Also, let me know if the color conversions are inaccurate.  REMEMBER these conversions ONLY work if you are utilizing a background color other than white (in design mode) in AutoCAD.

AutoCAD Color Index (ACI) and Equivalent RGB (for background colors other than white)

I found that other sites were not accurate with the color conversion so here ya go!
