I am trying to prepare a paper for IEEE Open Access that uses \documentclass{ieeeccess} ; its template (https://ieeeaccess.ieee.org/wp-content/uploads/2022/01/LaTeX.zip).

When I add use tikz package, I am having many Package xcolor Warning: Incompatible color definition warning messages. Is it possible to suppress this warning message?

simplified code example:

\documentclass{ieeeaccess}
%%%%%%%
\usepackage{tikz}  
\NewSpotColorSpace{PANTONE}
\AddSpotColor{PANTONE} {PANTONE3015C} {PANTONE\SpotSpace 3015\SpotSpace C} {1 0.3 0 0.2}
\SetPageColorSpace{PANTONE}%
%%%%%%%%%
\usepackage{cite}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{algorithmic}
\usepackage{graphicx}
\usepackage{textcomp}

I have identified a straightforward solution for this problem. Navigate to \documentclass{ieeeccess} and substitute \Requirepackage{color} with \Requirepackage{xcolor}. That's all you need to do.

I have found a fairly simple solution.

  1. Open ieeeaccess.cls
  2. Find every instance of \def\year
  3. Replace with \def\Year
  4. Save and rename the .cls file to avoid confusion with the original ieeeaccess.cls (see samcarter_is_at_topanswers.xyz's comment below)

and done.

  • I can already able to use tikz with ieeeaccess.cls , already have PANTONE lines in the question – alper Dec 13 '22 at 21:08
  • From what I see, your example works with no errors nor warnings using pdflatex. So what is the problem now? – anis Dec 14 '22 at 08:43

    @anis If you suggest to edit a class or package, please also always suggest to rename it. Getting help for future problems will be a nightmare if the user uses a modified without any indication of doing so in the log file and it also risks that different files with the same name will float around the internet. That's even more important for a class which is not included in the usual tex distributions. (depending on the license, renaming might even be a requirement) – samcarter_is_at_topanswers.xyz Dec 14 '22 at 13:13
  • Excellent point. i made an edit to clarify that point. Thank you. – anis Dec 14 '22 at 13:33
