Takeaways from previous discussions

Regarding the label "Indigo"

1. Indigo is the legitimate name of a dye, a chemical extract, and several well-defined colors from various color systems.
2. The extract, the dye, the segment of the rainbow labelled indigo, and the colors that commercial color companies label indigo are all different from one another.
3. None are absolutely authoritative.

Regarding the inclusion of color swatches

Including color swatches may or may not be useful at this point, unless another system gives another color the label "indigo" there are many variations on indigo and it does not appear useful to include them all, nor add others as they appear.

This is all in my IMHO

Wrong Color

Indigo is a dark shade of blue, but someone has it showing a shade of purple that's similar to indigo instead. --174.17.102.201 (talk) 01:19, 26 March 2017 (UTC)

No, it is not varied colors. It's various shades of blue, some of which a color blind person could confuse for purple. --174.17.102.201 (talk) 01:21, 26 March 2017 (UTC)

Yep. Indigo is the color of standard blue jeans as they were traditionally dyed with indigo (and now dyed with synthetic indigo). — al-Shimoni (talk) 00:07, 28 October 2017 (UTC)

Your showing purple. I'm not colorblind. I'm tetrachromatic. I can clearly see the colors better than others. It's purple. People without tetrachromacy mix up purples, and blues. They can't see the difference. --184.101.140.186 (talk) 20:25, 23 November 2019 (UTC)

Possible removal from list

Entries in List of colors: A–F contained links to this page.

The entries are :

• Dark imperial blue (#00416A)
• Dark imperial blue (#00147E)
• Imperial blue
• Japanese indigo

I don't see any evidence that these colors are discussed in this article and plan to delete them from the list per this discussion: Talk:List_of_colors#New_approach_to_review_of_entries

If someone decides that these colors should have a section in this article and it is added, I would appreciate a ping.--S Philbrick(Talk) 17:41, 22 August 2018 (UTC)

Changing the color code

#3F00FF is kinda bright so I think it makes more sense if we use #3800DF instead of 3F00FF since indigo always been considered to be a deep violetish-blue and #3800DF is kinda a deep color. --IndieTheFurry (talk) 03:31, 11 October 2020 (UTC)

Distinguishing indigo from it's neighbors

The following snippet from the current text of the article, makes little sense: "The human eye does not readily differentiate hues in the wavelengths between what are now called blue and violet. If this is where Newton meant indigo to lie, most individuals would have difficulty distinguishing indigo from its neighbors."

I'm not aware that most people have any trouble distinguishing blue from violet. I expect they find it even easier to distinguish cyan (Newton's "blue") from blue (Newton's "indigo"). If this snippet is trying to make some kind of point, it is failing to make it, and it does not give any source. I suggest we strike it. --Ericjs (talk) 01:21, 17 May 2021 (UTC)
