# Golf the colors of a rug
[tag:code-golf] [tag:kolmogorov-complexity]

## Background

The challenge is based on this rug:

[![Rug][1]][1]

Its colors seem very regular, but the pattern isn't obvious. However, it becomes visible when we move vertical stripes of the rug up and down:

[![Rug strips][2]][2]

All stripes are colored in the same way, but each stripe is offset by some height, except for a few irregularities. Also, the stripes have different widths.

First, we need to list all colors:
```
0: blue-ish white
1: lighter blue
2: darker blue
3: darkest blue
4: green-ish white (the color between the middle orange rows)
5: middle green
6: dark green
7: orange
8: light red
9: dark red
```
Now, we can lay a grid of cells of equal color over this image. I found that using a cell size of 73.5x129 pixels seems to be a good compromise between precision and compactness. This results in a 42x32 grid, which looks like this when overlayed over the rug:

Correcting for some perspective errors, we now can approximate the colors of this rug like this:

The color scheme shared by all stripes consists, from top to bottom, of these 42 colors: `[3, 3, 2, 3, 3, 2, 2, 0, 2, 2, 1, 1, 3, 1, 1, 5, 5, 6, 5, 5, 6, 6, 7, 6, 6, 7, 7, 4, 7, 7, 8, 8, 7, 8, 8, 9, 9, 8, 9, 9, 9, 9]`. (This already contains the information that some rows have different heights, by having multiple entries of the same color in a row.)

There are 18 stripes with widthes `[2, 3, 3, 3, 1, 1, 4, 2, 1, 6, 1, 1, 2, 2, 2, 3, 2, 3]`.
Their vertical offsets are `[3, 4, 3, 4, 2, 0, 2, 4, 7, 9, 10, 9, 5, 3, 5, 3, 4, 5]`, which means the first stripe starts at the color at index 3 in the common scheme, the second stripe at index 4 and so on. Starting from the respective start index, the next 32 colors are used; remaining colors (if any) are unused.

There are some irregularities in the rug. I didn't find a better way of expressing them except for listing their X and Y coordinates in the grid together with their colors:
```
X     [8,  9, 10, 19, 19, 12,  0,  1,  2,  3,  4,  2,  3,  4,  2,  3,  4,  5, 13, 14, 15, 16, 17, 18, 34]
Y     [18, 18, 18, 23, 24, 27, 31, 31, 29, 29, 29, 30, 30, 30, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31, 31]
Color [5,  5,  5,  0,  0,  8,  9,  9,  9,  9,  9,  9,  9,  9,  8,  8,  8,  9,  9,  9,  9,  9,  8,  8,  9]
```
They are included in this challenge to better reflect the rug and to increase difficulty a bit. 

## Challenge
Output this 42x32 grid of numbers from 0-9, each corresponding to the color of one cell of the rug:

## Rules
- The program should not take input.
- Formatting doesn't matter.
- This is [tag:code-golf], so shortest answer (in bytes) wins.

## Sandbox Questions
- Why doesn't the box with irregularities align?
- Would the challenge be more fun with or without having to include irregularities? I guess allowing both variants is not a good idea because solutions aren't comparable anymore.
