Here is my code:

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes,snakes}
\usepackage[html]{xcolor} 

\definecolor{rot}{HTML}{e40303}
\definecolor{xorange}{HTML}{ff8c00}
\definecolor{gelb}{HTML}{ffed00}
\definecolor{gruen}{HTML}{008026}
\definecolor{blau}{HTML}{004dff}
\definecolor{lilla}{HTML}{750787}


\begin{document}


\begin{tikzpicture}[x=0.026458cm,y=0.026458cm]
\fill[fill=rot](0,0)rectangle(750,70);
\fill[fill=xorange](0,0)rectangle(750,140);
\fill[fill=gelb](0,0)rectangle(750,210);
\fill[fill=gruen](0,0)rectangle(750,280);
\fill[fill=blau](0,0)rectangle(750,350);
\fill[fill=lilla](0,0)rectangle(750,420);
\end{tikzpicture}

\end{document}

I don't know why it doesn't do what I wanted it to do. Hopefully some of you can help?

Kind regards!

    Could you please detail more what you wanted to do? At least to me, it is not clear at all.

    I think we should properly ask this question as Drawing the gay pride flag. By the way it is also already in the TikZ manual. Search for pride

  • @percusse to clarify, a gradient version is included in the current manual. this is stepwise.

  • If you want to preserve the original golden ratio of the rainbow flag, you should use 77 in place of 70 as rectangle height.

  • @SeanAllred It is not a country flag. You can spot rainbow everywhere.

Some comments :

  1. xcolor is loaded by tikz, so don't reload it again,
  2. use capitals in color numbers,
  3. your last rectangle overlap the previous ones,
  4. you can make it shorter using foreach.

Here is the code : 

\documentclass[tikz]{standalone}

\definecolor{rot}{HTML}{E40303}
\definecolor{xorange}{HTML}{FF8C00}
\definecolor{gelb}{HTML}{FFED00}
\definecolor{gruen}{HTML}{008026}
\definecolor{blau}{HTML}{004DFF}
\definecolor{lilla}{HTML}{750787}

\begin{document}
  \begin{tikzpicture}[x=0.026458cm,y=0.026458cm]
    \foreach[count=\i] \col in {lilla,blau,gruen,gelb,xorange,rot}
      \fill[\col] (0,70*\i) rectangle +(750,70);
  \end{tikzpicture}
\end{document}

    Let's go :) \tikz\foreach[count=\i]~in{E40303,FF8C00,FFED00,008026,004DFF,750787}\definecolor{temp}{HTML}{~}\fill[temp](0,70*\i pt)rectangle+(750 pt,70 pt);

    @percusse \tikz\foreach[count=\i]~in{E40303,FF8C00,FFED00,008026,004DFF,750787}\definecolor{t}{HTML}{~}\fill[t]rectangle(750pt,70*(7-\i pt);, your turn ;)

  • @Kpym what does the "(0,70*\i) " make?

  • @Dr.HenrietteB.Fröhlich The (0,70*\i) sets the starting coordinate for each bar of the flag starting at the bottom: (0,70) then (0,140), then (0,210) etc.

    OK I give you golden ratio then :P \tikz\foreach[count=\i]~in{E40303,FF8C00,FFED00,008026,004DFF,750787}\definecolor t{HTML}~\fill[t](0,\i)|-(15,\i+1.545)|-(0,\i); ... Aargh I gave away the trophy haha I should have thought about it anyway let's see if you can find it :)

The previous color is overwritten by the next larger rectangle, probably you want something like:

\documentclass[tikz]{standalone}

\definecolor{lila}{HTML}{8800bb}
\definecolor{blau}{HTML}{0000FF}
\definecolor{hellblau}{HTML}{88bbdd}
\definecolor{gruen}{HTML}{66bb44}   
\definecolor{gelb}{HTML}{FFee00} 
\definecolor{orange}{HTML}{FF4411}
\definecolor{rot}{HTML}{FF1100}   

\begin{document}

\begin{tikzpicture}[x=0.026458cm,y=0.026458cm]
\fill[fill=lila](0,0)rectangle(750,70);
\fill[fill=blau](0,70)rectangle(750,140);
\fill[fill=hellblau](0,140)rectangle(750,210);
\fill[fill=gruen](0,210)rectangle(750,280);   
\fill[fill=gelb](0,280)rectangle(750,350);    
\fill[fill=orange](0,350)rectangle(750,420);
\fill[fill=rot](0,420)rectangle(750,490);   
\end{tikzpicture}

\end{document}

Result

Remark for xcolor 2007/02/21 v2.11

This version has a bug with the effect that the lowercase f does not work inside the values for the color model HTML.

Workarounds:

  • Using uppercase letters. Example: \definecolor{gelb}{HTML}{FFEE00}

  • After package xcolor is loaded, the macro \@hex@@Hex needs to be patched, which converts lowercase hex digits to uppercase hex digits, needed for TeX's hex syntax with the double quote:

    \usepackage{etoolbox}
\makeatletter
\patchcmd\@hex@@Hex{f\else}{F\else}{}{}
\makeatother

In case you would like the flag to fly...

\documentclass[tikz, border=5pt]{standalone}
\usetikzlibrary{shapes.symbols,positioning}

\definecolor{rot}{HTML}{e40303}
\definecolor{xorange}{HTML}{FF8c00}
\definecolor{gelb}{HTML}{FFed00}
\definecolor{gruen}{HTML}{008026}
\definecolor{blau}{HTML}{004dFF}
\definecolor{lilla}{HTML}{750787}

\begin{document}

\begin{tikzpicture}[x=0.026458cm, y=0.026458cm, tape bend height=20, shape=tape, text width=750, minimum height=70, inner sep=0pt, node distance=-1pt]
  \node (rot) [fill=rot] {};
  \node (oren) [fill=xorange, below=of rot] {};
  \node (melyn) [fill=gelb, below=of oren] {};
  \node (gwyrdd) [fill=gruen, below=of melyn] {};
  \node (glas) [fill=blau, below=of gwyrdd] {};
  \node [fill=lilla, below=of glas] {};
\end{tikzpicture}

\end{document}

flying pride

Or, more concisely using a \foreach loop:

\documentclass[tikz, border=5pt]{standalone}
\usetikzlibrary{shapes.symbols,positioning}

\definecolor{rot}{HTML}{e40303}
\definecolor{xorange}{HTML}{FF8c00}
\definecolor{gelb}{HTML}{FFed00}
\definecolor{gruen}{HTML}{008026}
\definecolor{blau}{HTML}{004dFF}
\definecolor{lilla}{HTML}{750787}

\begin{document}

\begin{tikzpicture}[x=0.026458cm, y=0.026458cm, tape bend height=20, shape=tape, text width=750, minimum height=70, inner sep=0pt, node distance=-1pt]
  \node (rot) [fill=rot] {};
  \foreach \i [remember=\i as \j (initially rot)] in {xorange,gelb,gruen,blau,lilla}
  \node (\i) [fill=\i, below=of \j] {};
\end{tikzpicture}

\end{document}

Adjusting the height a little:

fflag pride 2

\documentclass[tikz, border=5pt]{standalone}
\usetikzlibrary{shapes.symbols,positioning}

\definecolor{rot}{HTML}{e40303}

\definecolor{gruen}{HTML}{008026}
\definecolor{blau}{HTML}{004dFF}
\definecolor{lilla}{HTML}{750787}

\begin{document}

\begin{tikzpicture}[x=0.026458cm, y=0.026458cm, tape bend height=20, shape=tape, minimum width=750, minimum height=100, inner sep=0pt, node distance=-1pt]
  \node (rot) [fill=rot] {};
  \node (oren) [fill=xorange, below=of rot] {};
  \node (melyn) [fill=gelb, below=of oren] {};
  \node (gwyrdd) [fill=gruen, below=of melyn] {};
  \node (glas) [fill=blau, below=of gwyrdd] {};
  \node [fill=lilla, below=of glas] {};
\end{tikzpicture}
