Please note that the question of whether to spell the subject of this article as color or colour is covered by the Manual of Style and American and British English spelling differences. Proposals about spelling should be raised at Wikipedia:Village pump (policy). This talk page is for discussing the subject matter of its article. Comments about the spelling of color or colour may be regarded as off-topic and removed.

Specifically: Wikipedia:Manual of Style#National varieties of English:

“

Stay with established spelling -- If an article has been in a given dialect for a long time, and there is no clear reason to change it, leave it alone. Editors should not change the spelling used in an article wholesale from one variant to another, unless there is a compelling reason to do so (which will rarely be the case). Other editors are justified in reverting such changes. Fixing inconsistencies in the spelling is always appreciated.

”

Also: Wikipedia:Perennial proposals#Enforce American or British spelling:

“

Proposal: For consistency's sake, we should pick one style of spelling (British or American, generally) and stick with it.
Reason for previous rejection: It is wildly impractical and there is no agreement on which style should be chosen, which has in the past resulted in repeated, needless edit warring.

Why does a rainbow appear when light goes through a prism?

White light has a combination of different colors. Such as red, orange, yellow, green, blue, indigo, and violet. All the colors have different wavelengths. When light moves through a prism, all the colors in the light go in all different directions. When they go in different directions, it becomes a rainbow. Here's what happens inside a prism: Violet have the shortest wavelength, so it moves downward. Indigo has the second shortest wavelength, so it moves a little more up than violet. Blue has a medium wavelength, so it moves a little more up than indigo. Green also has a medium wavelength, but it is a little bigger than blue. It moves more up than blue. Yellow has a big wavelength, so it moves higher up than green. Orange has a big wavelength, but bigger than yellow. It moves more up than yellow. And finally, red has the biggest wavelength. It moves the highest in the prism. That is what happens inside a prism. If you have a dreamcatcher that is made of glass, that is a prism. That's why you see rainbows up on your ceiling every morning. Do you have anything else that is a prism in your room? If you are not sure, ask your parents, they will tell you, I promise! If they aren't sure, go back on wiki, and I will tell you! — Preceding unsigned comment added by 68.9.245.187 (talk) 21:03, 13 March 2019 (UTC)[reply]

Semi-protected edit request on 23 June 2020

It is requested that an edit be made to the semi-protected article at Color. (edit · history · last · links · protection log)

This template must be followed by a complete and specific description of the request, that is, specify what text should be removed and a verbatim copy of the text that should replace it. "Please change X" is not acceptable and will be rejected; the request must be of the form "please change X to Y".

The edit may be made by any autoconfirmed user. Remember to change the |answered=no parameter to "yes" when the request has been accepted, rejected or on hold awaiting user input. This is so that inactive or completed requests don't needlessly fill up the edit requests category. You may also wish to use the {{ESp}} template in the response. To request that a page be protected or unprotected, make a protection request.
