Symbolism?[edit]

Why is there an entire section in here devoted to "Symbolism" that says that amber is "symbolic" of "energy"? It makes no sense whatsoever. --Dreadpiratetif 22:47, 4 May 2006 (UTC)

In literature, colors are usually symbolic, or more accurately, representive of certain traits, etc. For example, purple is symbolic for royalty, green for spring or life, black/white for death/life, yellow for cowardice, and so on. If you see someone wearing yellow (in literature), he's a coward. A peasant wearing purple might have a tendancy to act like royalty. —Preceding unsigned comment added by 75.57.140.157 (talk) 01:14, 10 February 2008 (UTC)

Visual representation[edit]

As in the Selective yellow article, the described approximation technique has yielded a color that is visually too red and insufficiently yellow. Here's a set of specs for a visual impression that seems more closely to match the colour of light produced by ECE-amber lighting devices:

Repeating my comment from the discussion page for Selective yellow, I think it is more appropriate to approximate the colour of the light (as it would appear when projected on e.g. a white surface) rather than trying to describe the colour of whatever filter is used to attain that colour (e.g. headlamp lens or filter balloon, reflector coating, etc.), for the appearance of such optical elements is very widely variable depending on the filtration technique used and the filter's placement within the optical system.

There should probably be reference to old ECE Amber being supplanted by new ECE Yellow, a change which was made primarily to accommodate and facilitate the transition to LED signalling devices. Scheinwerfermann 00:05, 17 December 2005 (EST)

As per my comment there, the colour specification is for the colour of the light. By my reading of the UNECE specs, the definition of amber was expanded in the last couple of years – the article shows the current one & you'll see the old one in the history. I assumed that this change was made to accommodate LEDs. Is there a separate "ECE Yellow" rather than just the new amber definition? That swatch just looks yellow to me, btw - the one on the article looks far more like an indicator on my display. I'd suggest a photo, like selective yellow. --KJBracey 11:08, 17 December 2005 (UTC)
Sorry, you're right regarding ECE "Amber" vs. "Yellow". The English-language ECE Regulations still refer to "Amber" despite that colour's recent expansion to accommodate LED and other non-filament light sources. What I was thinking of was France's objection a couple of years ago to the use of "Ambre" in the French-language ECE Regulations. They wanted it changed to "Jaune Auto" ("Automotive Yellow") and while I haven't checked lately, I think they probably got their wish. There is an ECE "Fog Lamp Yellow" which is a somewhat more permissive variant of ECE Selective Yellow. Scheinwerfermann 12:34, 11 January 2006 (EST)
Whoops, looks like I was right about the colour specs being changed under ECE Regs; I just garburated the description of what happened. Old ECE Amber was defined as:
limit towards red: y ≥ 0.398
limit towards green: y ≤ 0.429
limit towards white: z ≤ 0.007
But, as of Rev3 Am1 & Am2 of Reg 6, and Rev4 of Reg 37, Amber has been redefined thus:
limit towards green: y ≤ x - 0.120
limit towards red: y ≥ 0.390
limit towards white: y ≥ 0.790 - 0.670 x
This is identical to the SAE "Yellow" spec. I am not too pleased at this loosening of the specification, but they didn't ask for my vote. Scheinwerfermann 17:56, 5 July 2006 (UTC)

Where on the color wheel?[edit]

The first sentence of the lede of this article states that amber is located on the color wheel midway between yellow, orange and red. That's wrong in one way or another; it's not possible for a thing to be between more than two other things. Images of color wheels here on Wikipedia and elsewhere don't seem to call out amber per se, so somebody please point at a color wheel that does, or fix the first sentence so it makes sense and reflects reality. —Scheinwerfermann T·C08:08, 29 September 2012 (UTC)
