Qatar's Colors

Is it really fair to put Qatar's flag under red and white? Its maroon and white. Costley51 (talk) 20:48, 3 May 2011 (UTC)Christina[reply]

How about a list of counties by prettiness of national flags? DSuser 16:51, 27 July 2007 (UTC)[reply]

This article looks pretty indeed. And I would be interested in the List of countries by prettiness of national flags. 80.123.210.172 (talk) 10:53, 17 January 2009 (UTC)[reply]

New Discussion

A discussion has been started at Wikipedia talk:WikiProject Countries/Lists of countries which could affect the inclusion criteria and title of this and other lists of countries. Editors are invited to participate. Pfainuk talk 12:06, 17 December 2008 (UTC)[reply]

Countries?

Countries such as Wales, Hong Kong ... Nice. But no Japan... —Preceding unsigned comment added by 72.229.244.7 (talk) 01:40, 27 July 2009 (UTC)[reply]

Missing Iran

How can you forget to list IRAN!!!! The first world empire and the regional power of the ME for 2500 years! —Preceding unsigned comment added by 24.80.113.143 (talk • contribs) 23:25, April 28, 2010 (UTC)

Rewriting

I think that since the article is overloaded, it should only include sovereign states. Subsections should also be sorted alphabetically. Feel free to comment. Maimai009 13:35, 16 March 2011 (UTC)[reply]

Sorting criteria?

What exactly constitutes a flag "with other color symbol"? Why is, for example, San Marino sorted as "blue and white with other color symbol", but Liechtenstein as "blue, red, yellow and black"? Some countries like Croatia are even listed twice. Seems rather inconsistent to me. Huon (talk) 00:35, 27 October 2011 (UTC)[reply]

You're right, this article seems to lack consistency. I think it needs to be cleaned up. I wanted to do it a year ago, but I just forgot about it. Here are the things I want to change in order to improve it:

First things first, I think it would be a good thing to exclude every non-sovereign state. The article is overloaded thus practically unreadable as it is now. Restricting inclusion would prevent any minor state (non sovereign), region, island or whatever to appear on the list. Actually, only states featured in the List of sovereign states should appear in the article.
The main problem with the sorting criteria is that many flags have emblems or symbols on them. In my opinion, there are three cases:

Emblems are significant to the design of the flag, and have one distinctive colours. Each colour should be considered in the classification.

*Example:*
Country	Colours
Albania	Red, black
Japan	White, red
Syria	Black, red, white, green
South Korea	White, red, blue, black

Bold: emblem colours.

Emblems are significant to the design of the flag, but have many colours. Only the main colour should be considered.

*Example:*
Country	Colours
Portugal	Green, red, yellow, ~~blue, white~~
Belize	Blue, red, white, ~~green, others~~

Bold: main emblem colour.

~~Strikethrough~~: non significant emblem colours.

Emblems are not significant to the design of the flag. They shouldn't be considered.

*Example:*
Country	Colours
Malta	Red, white, yellow, ~~grey~~
Nicaragua	Blue, white, ~~yellow, others~~

~~Strikethrough~~: non significant emblem colours.

I am aware that this system is far from perfect and that some countries may fall under more than one of the aforementionned cases, but it's better that nothing, hence better that the current free for all system.

I have a doubt over how these countries should be classified : Latvia, Qatar, Sri Lanka, Eswatini, due to the usage of a dark red color, sometimes close to brown. But in my opinion, I would classify them as red because we shouldn't be too specific.

Thank you to give your opinion. Maimai009 20:56, 13 February 2012 (UTC)[reply]

Armenia Missing as well

Just pointing out ;) — Preceding unsigned comment added by 95.97.74.147 (talk) 22:22, 8 January 2012 (UTC)[reply]

Added it. Thanks! Huon (talk) 22:52, 8 January 2012 (UTC)[reply]

Libyan flag

Libyan flag was under red, black, green category while it is red, black, green, and white, so I removed it to the latter category. — Preceding unsigned comment added by 41.254.5.244 (talk) 15:35, 13 January 2012 (UTC)[reply]

Bhutan

There was some confusion about the flag of Bhutan. 62.78.202.58 recently changed it from red, white and orange to red, white and yellow, but the flag article says it's actually orange, white and yellow. Part of the uncertainty may be due to a change in the flag's coloring in 1968 or 1969, changing the lower half from red to orange. Anyway, I renamed the section accordingly and put it under "yellow and white" to conform to the rest of the sorting scheme. It looks a little off-color compared to the other "yellow" flags, though - thoughts? Huon (talk) 15:47, 2 August 2012 (UTC)[reply]

Sources describe it as yellow eg. World Factbook. We can't divide this article down into the minutiae of different shades of each colour, so I think it's perfectly fine in with other types of Yellow. CMD (talk) 16:33, 2 August 2012 (UTC)[reply]

South Sudan is missing

A country already a year old. I tried to do it myself, but the Edit page just scared me, it's clearly beyond my capabilities. — Preceding unsigned comment added by 80.2.127.96 (talk) 09:49, 13 August 2012 (UTC)[reply]

I've added it; thanks for the note! Kiribati was only added last week or so; I wonder what else is missing. We should probably compare this list with one of all countries. Huon (talk) 11:28, 13 August 2012 (UTC)[reply]

Suggestion for list layout (possibly in connection to comments above)

Write a program to extract the amount of R, G, B, brightness/darkness, and possibly composite colours, from each national flag (i.e., the amount of each in the entirety of its pixels), and put the values in a sortable table. I would experiment with it myself, but I don't know how to measure the sub-colours, e.g. yellow etc. 83.6.167.209 (talk) 05:04, 28 February 2014 (UTC)[reply]

There could also be a column for the average colour of the flag, to allow sorting them colour-continuously. 83.6.167.209 (talk) 05:06, 28 February 2014 (UTC)[reply]

Of course, in more accordance to the present system, there could also be a table with some basic colours. Then e.g. a program could extract the flag's most prominent colours by area (just by counting the pixels with them, either strictly or with some room of similarity), and then humans would arbitrarily assign the percentages to the respective basic column. It would work like this (the table is imperfect, e.g. the country cells should be headers, but the compact wikimarkup doesn't seem to support this, headers should be title=''d, etc.):

country	R	Y	B	W	B
France	33%		33%	33%
Germany	33%	33%			33%
Poland	50%			50%

The difference between it and the first table I described is the second table would contain assignments that are human and arbitrary, while the first one would contain the actual numerical values of the colours in the images. 83.6.167.209 (talk) 05:30, 28 February 2014 (UTC)[reply]

Of course, I'm not opposing the idea of breakup of flags with respect to meaning of their elements (emblems etc.)--that should be done too. 83.6.167.209 (talk) 05:50, 28 February 2014 (UTC)[reply]

For plain striped flags it's easy to derive the percentages of each color ( ${\frac {100}{3}}\%$ for plain tribands like the German flag). For flags like that of Japan a bit of geometric reasoning is needed but it's still doable ( $6\pi \%$ red and $(100-6\pi )\%$ white in this case). Though good luck calculating the color composition of the flag of Serbia... SiBr₄ (talk) 07:42, 28 February 2014 (UTC)[reply]

Thank you, but I just meant brute calculation, as the program would be run on my PC. In pseudocode, I just meant for each pixel, colours[pixel.colour]++; for each colour, colours[colour] /= total_pixels_count;. (Or, with "room for similarity", the percentages could be additionally re-counted, including similar pixels in the count too). 83.6.167.209 (talk) 12:49, 28 February 2014 (UTC)[reply]

Do you know of a program that can determine the color of each pixel of an image like that? Also, if you're using raster images of the flags to find the color of each pixel, wouldn't such a program conclude the flag of France (for example) is partially light blue and pink because of anti-aliasing effects? Maybe the percentages can be calculated manually for the "easier" flags and approximated numerically using an automated program for the "harder" ones. SiBr₄ (talk) 13:24, 28 February 2014 (UTC)[reply]

Yes, it's easy, see e.g. http://pl1.php.net/imagecolorat#refsect1-function.imagecolorat-examples (I'm playing with it right now). And yes, anti-aliasing is possibly a problem; that's why I suggested "similarity" in identification of colours, and also why, for my playing, I fetched the biggest available PNGs (that didn't exceed the "nominal size" of the original SVG), usually ca. 1000 px. 83.6.167.209 (talk) 14:15, 28 February 2014 (UTC)[reply]

Added the composition table to the article.

http://pastebin.com/N29Cg4i7 - code.
http://pastebin.com/734EqxjV - code-output of the script. I'm posting it, because it also contains the most common colours, as I suggested above, in case someone wants to use it (concerning the anti-aliasing, it should be easy to programmatically collect them into "nearly-same" groups).
