In 2015 the Portland International Airport began the replacement of their iconic carpet. I want you to write a program to draw their old carpet in as few bytes as possible.

The carpet:

One tile

Specifications

  • Here is a link to a scalable pdf image of one tile. Your output should match the relative dimensions and placement of that image.

  • All colors in your final image should be within 15 of every RGB value in the specified image. These are listed below for your convenience.

                Red   Green Blue
    Teal:       0,    168,  142
    Magenta:    168,  108,  185
    Orange:     247,  58,   58
    Light Blue: 90,   166,  216
    Dark Blue:  0,    77,   117
    
  • Your output must be at least 150x150 pixels and should be square. If you choose to output in a scalable format like a vector image you should match the image exactly.

  • You may output the image in any preexisting image format.

  • This is so you should aim to minimize the number of bytes in your code.

Try it Online!

Explanation

A good deal of the code is a wrapper:

\documentclass{standalone}\usepackage{xcolor,tikz}\begin{document}\tikz{...}\end{document}

This is a slight variation on the standard Tikz wrapper in that it also has the line \usepackage{xcolor} so that we can create the colors properly.

The first thing that is done is line width=20,every node/.style={minimum size=20}] which sets the lines and nodes to be the proper size.

Once that is done we define the colors we will be using for the various parts of the image:

\definecolor{t}{RGB}{0,168,142}\definecolor{m}{RGB}{168,99,185}\definecolor{o}{RGB}{247,58,58}\definecolor{b}{RGB}{90,166,216}\definecolor{d}{RGB}{40,77,117}

Now that everything is set up we paint the background to our canvas teal:

\fill[t](-7.5,-7.5)rectangle(7.5,7.5);

(I wont include an image of this because it is just a teal square, but I will be including images of each other step)

The first node we add is the orange node just left of the center of the canvas.

\draw(-1,0)node[fill=o]{};

An Orange at Sea

Now we will draw the light blue and magenta nodes. There are 7 blue nodes and 4 blue nodes, but we can draw extra nodes that will be covered up by lines later on so we will draw 7 of each.

\foreach\x in{1,...,7}{
    \draw(-\x,-1)node[fill=m]{};
    \draw(0,\x)node[fill=b]{};
}

Forked Paths

Now we will draw all the groups of 3 dots using a single \foreach loop

\foreach\x in{1,...,3}{\draw(\x,\x)node[fill=d]{};\draw(3+\x,-3-\x)node[fill=d]{};\draw(-3-\x,3+\x)node[fill=d]{};\draw(4+\x,1)node[fill=o]{};}

Scattered dots

Now we draw the right line. This line will be a simple line with offsets of .35 in each direction to match the size of a node.

\draw[d](.65,0)--(7.35,0);

Collision

Now we must draw in the dark blue lines and squares on the x-axis. We will draw them with one line using a custom dash pattern.

This pattern is [dash pattern=on20off8.5on162.5off8.5] This creates a square with a long solid tail. Our line will start from the bottom and will not quite cover 2 cycles of the pattern.

\draw[d,dash pattern=on20off8.5on162.5off8.5](0,-7.35)--(0,3.35);

Final

And now we are done.

  • \$\begingroup\$ I don't know Tikz at all, so can't help with that :( However, if I understood your rule about "within 15 of every RGB" right, you can change 108 to 99, since the error is under 15. \$\endgroup\$ – Yytsi Feb 12 '17 at 14:54

    \$\begingroup\$ You may be right, but even the description of the tag kolmogorov-complexity on codegolf.stackexchange.com/tags/kolmogorov-complexity/info mentions a complex string, which shortest representation might be to print it literally. If a literal string is considered the "worst case solution" to a string based code-golf, a literal image file could be considered a "worst case solution" to an image based code-golf. Edit: I only posted the file, because I was surprised that it was actually shorter than the other solutions posted earlier.

Mathematica, 285 bytes

e={1,1};r=RGBColor["#"<>#]&;c=Cuboid;s=c[3#-e,3#+e]&;a=Array;b=a[s[{1,-1}#]&,3,#]&;Graphics@{r@"0a8",c[-23e,23e],r@"a6b",a[s@{-#,-1}&,7],r@"f33",a[s@{#,1}&,3,5],s@{-1,0},r@"5ad",a[s@{0,#}&,4,4],r@"057",a[s[e#]&,4,0],b@4,b[-6],s@{0,-7},{-1,2}~c~{1,10},{-1,-2}~c~{1,-19},{2,-1}~c~{22,1}}

Easier to read:

 1  c = Cuboid; e = {1, 1};
 2  s = c[3 # - e, 3 # + e] &;
 3  a = Array; b = a[s[{1, -1} #] &, 3, #] &;
 4  r = RGBColor["#" <> #] &; 
 5  Graphics@{
 6   r@"0a8", c[-23 e, 23 e],
 7   r@"a6b", a[s@{-#, -1} &, 7],
 8   r@"f33", a[s@{#, 1} &, 3, 5], s@{-1, 0},
 9   r@"5ad", a[s@{0, #} &, 4, 4],
10   r@"057",
11    a[s[e #] &, 4, 0], b@4, b[-6], s@{0, -7},
12    {-1, 2}~c~{1, 10}, {-1, -2}~c~{1, -19}, {2, -1}~c~{22, 1}
13  }

Lines 1–3 define short names for functions, the most important of which is s which draws a square centered at the coordinates it receives (really 3 times its coordinates, for appropriate scaling). Line 4 defines a color function using Mathematica's "shortcut" RGB system: RGBColor["#xyz"], where xyz are hexadecimal digits, stands for RGBColor[{17x, 17y, 17z}] (so that each coordinate has 16 equally spaced options running from 0 to 255). The first commands on lines 6–10 switch the current color, using the shortcut colors that are closest to the designated five colors (no value is off by more than 8 when we round to the nearest multiple of 17).

Line 6 draws the large teal square. Line 7 draws the line of magenta squares, Line 8 draws the line of orange squares and the single orange square. Line 9 draws the line of light blue squares. Line 11 draws the three diagonal lines of dark blue squares, as well as the single dark blue square at the bottom. Finally, line 12 draws the three long dark blue rectangles. The output is below:

Portland

(Golf tip: the command Cuboid, which is intended for 3d graphics objects, works just fine in 2d and is shorter than Rectangle.)

Explanation

An array of arrays is mapped to function a, creating clones of the rect in the HTML, inserting them after the initial rect and setting their fill, x, y, width & height attributes. Each array contains values for those attributes, in that order, with any missing values being set by the default parameters of a. The seemingly unnecessary r.id++ allows the use of cloneNode() while ensuring there is only ever 1 rect with an id of c; this saves the need to use the ridiculously expensive document.createElementNS("http://www.w3.org/2000/svg","rect").
