Official Colors?

Should we adapt the official colors from the International Commission of stratigraphy? You can put your comment below, yes or no and/or reason for yes and no. 24.218.110.195 (talk) 21:48 08 April 2013 (UTC) 5:48pm 04/08/2013 EDT.

No, I think not: it looks good as it is. On a screen (as opposed to a wallchart) it's best not to get too fancy. Thank you very much for doing the work! Macdonald-ross (talk) 07:08, 9 April 2013 (UTC)[reply]

Here is what it'll look like with official colors. It is very similar the ones on English Wikipedia. I show it below my comment. And for here I autocollapse the table 24.218.110.195 (talk) 3:00 16 April 2013 (UTC) 11:00pm 04/15/2013 EDT.

No. The colours distract attention from where it should be, the text, to the chart. Charts should not dominate the page. It's time to leave this alone and move on. Macdonald-ross (talk) 04:40, 16 April 2013 (UTC)[reply]

I see that the color template Template:Period color was suppose to be for colors of geology (geologic time) articles. It contains the colors (code) for every geologic time including stages such as Phanerozoic ,Kimmeridgian ,Precambrian ,Cenozoic ,Tonian, Lopingian and much more. Right now no geology articles or geology templates use this excluding talk pages. In fact no articles use this template at all. 24.218.110.195 (talk) 13:14 16 April 2013 (UTC) 9:14am 04/16/2013 EDT.

NOTE:The small collapsed tables will only be seen properly if all are shown or not. 24.218.110.195 (talk) 0:38 28 April 2013 (UTC) 8:38pm 04/28/2013 EDT.

In North America, the Carboniferous is subdivided into Mississippian and Pennsylvanian sub-periods or epochs. Discoveries in the past quarter century have substantially changed the view of geologic and paleontologic events just before the Cambrian. The term Neoproterozoic is used now, but older writers might have used 'Ediacaran', 'Vendian', 'Varangian', 'Precambrian', 'Protocambrian', 'Eocambrian', or might have extended the Cambrian further back in time. Dates are slightly uncertain, and differences of a few percent between sources are common. This is because deposits suitable for radiometric dating seldom occur exactly at the places in the geologic column where we would most like to have them. Dates with an * are radiometrically determined based on internationally agreed GSSPs. Paleontologists often refer to faunal stages rather than geologic periods. The faunal stage nomenclature is quite complex. See http://flatpebble.nceas.ucsb.edu/public/harland.html for an excellent time ordered list of faunal stages. In common usage the Tertiary-Quaternary and Palaeogene-Neogene-Quaternary are treated as periods. The term 'age' (e.g. 'Neogene Age') is sometimes used instead of 'period'. The time shown in the "Years Ago" column is that of the start of the Epoch in the "Epoch" column.

I, or anyone should maybe be bold about

"Neogene (2.588–23.03 mya".--I am thinking it should start by saying: "*"Neogene (2.588 million years ago–23.03 mya ...". Anyone can be bold and make that change. 89.8.123.15 (talk) 17:13, 6 March 2022 (UTC)[reply]
