Random Hex Color Codes AutoCAD Color Index (ACI) RGB equivalents UNIX Standard Colors

The table below contains hexadecimal and decimal RGB codes for the 256 colors in the AutoCAD Color Index (numbers 0-255). The information contained in this table was obtained from this page.

I had a bear of a time trying to find this information for a project at work, and since I already had it in a nice format in Excel, turning it into an HTML table seemed like a logical and easy thing to do to maybe help others in the future. OK, so not many people outside of the International Space Station program have to worry about conflicting with standardized colors for carbon dioxide (191) in an engineering drawing, but one never knows when this info will come in handy. I've received a number of nice notes from people over the years who've found this page useful, and I'm just glad to help. =)

The coded colors are shown in the ACI number cell for each row. Note that these are not browser-friendly colors and will probably dither (i.e. look wrong in a browser).
