File talk:Flag of Thailand.svg
My revert (16 Nov 2006)
[编辑]I reverted to the Gabbe's 7 January 2006 version. The version by Plenz was based on Wikipedia:th:Image:Thailand flag large.png, which is now deleted so I wouldn't know any details regarding its accuracy. The Flag Act of 1979 only specifies the colours as dark blue (น้ำเงินแก่), white and red, and Gabbe's version more closely resembles the flags seen flying in Thailand.

- The above observation is, of course, my own opinion. Upon closer inspection, it seems the blue usually used is somewhere in between, darker than Plenz's version but brighter than Gabbe's; the red is also brighter and more saturated. Paul C 12:57, 18 November 2006 (UTC)

Official colours announced (2017)
[编辑]A new law has just been announced that gives standard recommended CIELAB colour values. I have no idea how Lab or CIELAB works, but the announcement can be found here. Pinging Zscout370 and Fry1989. Could you take a look, please? --Paul_012 (留言) 12:56, 4 October 2017 (UTC)
The values are given in CIELAB D65 as follows:
Colour | L* | a* | b* | ΔE* |
---|---|---|---|---|
Red | 36.4 | 55.47 | 25.42 | Not exceeding 1.5 |
White | 96.61 | -0.15 | -1.48 | Not exceeding 1.5 |
Blue | 18.63 | 7.89 | -19.45 | Not exceeding 1.5 |
The document describes them as recommended standard values for the measurement of physical cloth flags. It also specifies that such measurements shall be made using a colorimetric spectrophotometer with 45/0 or d/8 method, using the mode specular exclude; SCE (in case of d/8 method, the sphere diameter must be no less than 152 mm), artificial light source and observer angle D65/10°. It also mentions UV filtering and cites ASTM E1164 as the relevant standard. --Paul_012 (留言) 20:09, 11 February 2018 (UTC)
- Found RGB values at https://www.nstda.or.th/th/nstda-knowledge/11557-thaiflag-color . Uploaded as File:Flag of Thailand, (2017 official colours).svg --Paul_012 (留言) 20:24, 11 February 2018 (UTC)
{{Edit request}} Requesting to overwrite the file with File:Flag of Thailand, (2017 official colours).svg, per the above info. --Paul_012 (留言) 20:29, 11 February 2018 (UTC)
完成 Thank you! -- User: Perhelion 09:23, 14 February 2018 (UTC)
- I agree with the change as well; I have been very busy so if anything urgent like this, please email me in the future. :) User:Zscout370 (Return fire) 10:49, 15 February 2018 (UTC)
- It's inappropriate to cite LAB values intended for a physical object and then transform them into an RGB colour space using an online calculator. It doesn't make any sense to make conversions like that. Consider what it would mean for File:Flag of Germany.svg. If you take empirical measurements of a physical German flag, the black third will never be perfectly black because a perfectly black pigment is physically impossible. But the SVG representation of the German flag uses #000 because computer screens are not dyed pieces of cloth, they are emissive. #000 is a directive to "emit the minimum possible light". Look at the Thai source document cited as the reason for choosing these RGB values: it has a big image of a Thai flag in it and the colours they are using in the image are vastly different from the RGB values that result from the LAB -> RGB transformation, the red and the blue are more saturated and they use #FFF for white. http://www.ratchakitcha.soc.go.th/DATA/PDF/2560/E/245/1.PDF --Alextgordon (留言) 18:33, 9 March 2019 (UTC)
- Hmm. No online calculator was used (by me) in choosing the colours; the NSTDA's post previously did give explicit RGB conversion values, (see archived version), but it appears they were later removed. It's rather obvious they backtracked to clarify that there are currently no official for-screen RGB values. But we have nothing else to go by. The image example in the official proclamation is only given as a rough visual guide identifying the order of the stripes and clearly cannot be relied on, as it's nowhere near the LAB values, and even the proportions are incorrect. --Paul_012 (留言) 11:30, 10 March 2019 (UTC)
I think white is too darker
[编辑]I think white is too darker. (#F4F5F8
) So I suggested it change only pure white color to #FFFFFF
is better. What do you think? --Tcfc2349 (留言) 12:46, 17 February 2018 (UTC)
- So I once uploaded fixed file. If the request is finished, this can be deleted. --Tcfc2349 (留言) 12:51, 17 February 2018 (UTC)
未完成 Please see one above, we are going after ref, not personal view. We don't need endless reverting (of personal versions). -- User: Perhelion 15:08, 17 February 2018 (UTC)
- I am a little late to this discussion, but I will comment anyway.
- I agree with Tcfc2349.
- There is an unwritten standard on Wikipedia (and possibly the entire Web) in which black and white on flags are always represented with "#000" and "#fff".
- e.g. the white on the flag of Canada is officially only specified by the government with CIELAB parameters yet it never shown on the Web with any colour other than #fff.
- e.g. the black on the flag of Jamacia is specified by the government as "Pantone Black C" which according to the Pantone website is equivalent to #2d2926... yet it is never shown on the Web with any colour other than #000.
- Why do we have to have an exception here? MapGrid (留言) 05:26, 3 February 2022 (UTC)
