Talk:Monochrome

message: *It looks better now that some of the disambig entries have been moved to Monochrome (disambiguation), but it still has the look of a disambiguation page because of the numbering.  Can't it be separated by topic into sections rather than numbered?--Hraefen Talk 14:50, 31 August 2006 (UTC)
thread_title: Why does this article still look like a disambiguation page?

message: "In the physical sense, no real source of electromagnetic radiation is purely monochromatic, since that would require a wave of infinite duration."
Could someone further clarify this?  Please, either explain what it means to need a "wave of infinite duration" in order to produce a single frequency, or point to another article that speaks of this. 24.38.129.70 01:01, 9 January 2007 (UTC)
replies: text: The frequency spectrum of a signal (in this case a sine wave) is derived by taking its Fourier transform. The property follows from that.--Adoniscik (talk) 19:23, 23 January 2008 (UTC)
thread_title: Further clarification

message: The author says that monochromatic colour schemes are to be used with caution, among other things. (s)he cites no authority to back this up.
Personally, I don't agree with his/her opinion - but that's irrelevant.
I think a source should at least be cited to back up his claim.
I hope this helps someone somewhere

thread_title: Monochromatic Colour Schemes

message: In the heading, it is said that "... A monochromatic object has a single colour...". This seems to hint at color being an object property, which probably is not true since it is a property of light (emitted by an object). 
Further, I have a more general question about monochromatic referring to: "... radiation of a single wavelength ...", in the Theory section. Also at many other places in Wikipedia it is stated that monochrome refers to having waves a single wavelength. Color is perceived by receptors in the eye, with the eyeball filled by some liquid of a certain refractive index and speed of light. So, the wavelength will in general change when the light comes from outside into the eye, depending on the medium outside. The wavelength in the eye will depend on the frequency of the incoming light, and not fundamentally on the wavelength it has outside the eye. The color the eye detects is therefor fundamentally dependent on the light frequency, instead of it's wavelength. Is it therefor not more correct to say that monochrome refers to a signal of a single frequency? Or is this a matter of definition?

replies: text: You're right, but it is conventional to describe light by its wavelength (in vacuum).  For example, this book; "one-wavelength" characterizes the light, even though that wavelength varies with the index of the material the light goes through.

replies: text: Thanks, so it is a matter of definition. Kraaiennest (talk) 12:14, 23 February 2008 (UTC)

text: But how about this then, from Candela: "... The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian...". This suggest monochromatic waves emerge from an source of constant frequency. Kraaiennest (talk) 13:26, 23 February 2008 (UTC)
replies: text: Yes, that's also obviously true, and in general more precise.  But it's not the most conventional way to describe monochromatic. Dicklyon (talk) 17:23, 23 February 2008 (UTC)

text:  Also objects can be defined as monochromatic, in which case the light reflected from them generally would not be of a single frequency.  --jacobolus (t) 19:26, 23 February 2008 (UTC)
replies: text:  I think the theoretical definition on monochromaticity should be accessible on more pages, as many would not think to search for it, after reading the page on lasers. It would be a useful information to have, as that page, and many others relating to lasers, continue to state that is producing monochromatic light, which conflicts this definition.

thread_title: Monochrome definition

message: I am confused here. There is the word monochromatic, but also monochrome. Perhaps the definitions would be different. It seems to me that monochrome would be something with one color in different shades, such as monochrome photos and monochromatic would be somethinig with one color frequency and one shade. So, what is right? Is there any expert in language who could and would please help? Thanks, euaio  — Preceding unsigned comment added by Euaio (talk • contribs) 08:02, 9 May 2012 (UTC)

message: A shaded colour is a colour that has a % of black added to make it darker. A darker colour must only be referred to as a shade if black has been used to darken it. It should be referred to as a hue not a shade if another colour has been used to darken it ie: green added to red to darken it. Many people often mistakenly refer to a darker colour as a shade and I notice Wikipedia is guilty of this.  — Preceding unsigned comment added by 176.250.198.218 (talk) 14:11, 16 February 2014 (UTC)

message: This article definitely is a (bad) disambiguation page.Articles should be about concepts, not words.  The only concept that is represented by those words is "using only shades of a single color"; but that can be just one line at the top of the disamb page.  There are already articles about monochrome painting, monochrome photography, monochrome displays, etc., and this article seems to be duplicating (poorly) some of their contents.Moreover, monochromatic radiation and monochromatic light are concepts totally unrelated to those uses of "monochrome".The content of this article should be moved to those specific articles, and this entry should be replaced by a redirect to the disamb page. --Jorge Stolfi (talk) 05:34, 23 November 2021 (UTC)

thread_title: Definitely a (bad) disambiguation page

message: I propose merging monochromatic colors into Monochrome. The former is a low quality article that is poorly linked and offers almost nothing that is not in monochrome, monochromatic radiation or spectral color.Curran919 (talk) 22:26, 9 November 2022 (UTC)
