I have rendered a new 3D image of three spotlights shining on a wall. Would the new version be preferable to the old? ➧datumizer  ☎  00:34, 29 May 2019 (UTC)

:I think the old one looks better. I actually thought it was a photo, while yours looks more obviously faked. Dicklyon (talk) 03:35, 29 May 2019 (UTC)

The RGB color model is an additive color model and, therefore, is used on a {{color sample|#ffffff}}White surface in a dark area.

as stated in https://en.wikipedia.org/wiki/Wikipedia:FAQ/Contributing#Should_I_use_American_English_or_British_English?, "The official policy is to use British spelling when writing about British topics, and American for topics relating to the United States." as can be found out with a quick google search, RGB was created in London, England. Therefore we use British English — Preceding unsigned comment added by Germany FranceUK Australia Russia Latvia (talk • contribs) 02:01, 8 November 2021 (UTC)

:That is for topics closely associated with one country or the other (we would use British English in the article about the Queen's biography). This article does not meet that standard. For example, Isaac Newton is English, but the article on gravity uses American spelling. See the full guidelines on this at WP:ENGVAR, which supersedes that FAQ you linked. In particular, see MOS:RETAIN. There are no strong national ties here, so the spellings should be left as they are. - MrOllie (talk) 02:09, 8 November 2021 (UTC)

::Sorry for the late response, but can you please explain why we should use the spelling of one specific country and not the standard version used by every other country. Or is it just you aren't aware that not everyone is american and revert useage of non-american spelling because you can't agknologe other cultures. 11:19, 10 November 2021 (UTC)Germany FranceUK Australia Russia Latvia (talk)

:::Wikipedia had a large amount of edit warring and argument about this earlier in its history, and the compromise that was reached (defined in MOS:RETAIN) is that whatever spelling style was used when the article was first written would be kept, barring some very limited exceptions. The Americans are getting RGB color model, the Brits are getting Aluminium, etc. - MrOllie (talk) 12:56, 10 November 2021 (UTC)

::::Well I don't entirely think that's fair i think the system is fair where some version of english get each thing but i think that brazil can get football australia can get colour new zealand can get labour america can get eraser etc. i think that is more fair that each country is represented as much as each other and not america gets 90% — Preceding unsigned comment added by Germany FranceUK Australia Russia Latvia (talk • contribs)

::::: Wikipedia is not a nationalistic contest. The goal is making an encyclopedia, not proving whose spelling dialect is superior. Other projects have other criteria for deciding on spelling, but MOS:RETAIN was settled on here as the most effective for writing a global encyclopedia by a pseudonymous/anonymous crew of volunteers. If you have problems with it please start by reading MOS:RETAIN, MOS:ENGVAR, and MOS:SPELL. If you have further concerns please take them up at WT:MOS, not here. –jacobolus (t) 07:15, 11 November 2021 (UTC)

I feel that the relation is not invertible. It is possible to state this (or say that is really invertible)? thanks 151.29.146.245 (talk) 01:18, 30 March 2025 (UTC)
