Template talk:Element color

Color changes
I have changed the palette (seven colors) for the PT discovery years templates Periodic table (discovery periods) and Periodic table (discovery periods, compact). Some of the old colors were a bit too dark to contrast with text, and the dark blue even made the frame illegible (synthetic?). new colors are in template:element color.
 * discovery era
 * I choose seven colors by hue. That is: what we call "color" in real life: from the rainbow. (RGB color numbers like #ffdead are not suitable for this; they look like an outcome of a calculation but not a 'color'). These seven hues are from the rainbow. The I applied the same "saturation" and "luminance" to each of them (a color has three independent settings, at least). Together they define a color by HSL.
 * By keeping the other two settings, Saturation and Luminance the same, over seven hues, the sphere is the same for all of them and I could set a lighter shade simply. That lightness is needed, because it is just a background color, that should contrast with the text.
 * These are the settings. Hues from red to pink: 0, 25, 37, 74, 111, 185, 222 (255 would be full circle to red). S and L are S=255 (max), L=220 (quite light, or say transparent).

Undiscovered occurrence (that is: mostly for theoretical period 8 & 9 elements) had a white border that did not show well in a PT with a light/whitish background. Now see Periodic table (extended, large). I set it to "no border" (in element frame/Undiscovered and in element color). IO think it looks nice now in Periodic table (extended, large) and others. Note that we can use ... now to get the color: this way we are more flexible. -DePiep (talk) 17:28, 14 April 2013 (UTC)

 * Minor changes

FYI: testing colors
When testing colors or set names, please add them to Element color/secondary. (add like )

In the testing location (say Template:Periodic table/test), use standard.

When a set name is not in main template, the template will automatically look up in the /secondary list. Once fit for mainspace, just move the name-color line to the main colortemplate (effect in your template will be unchanged). Double sharp@undefined -DePiep (talk) 18:26, 16 November 2020 (UTC)

h-block and i-block colours
A few decades ago, a few basic predictions were made for the h-block, for example. (Just as there are "triads" and "tetrads" in the d and f blocks, so she expected "pentads" and "hexads" in the g and h blocks.) Of course, the system gets wonky starting from the g elements, so it's not entirely clear if this will hold up.

There could be some valid uses (even if outside a PT) when listing subshells and colour-coding them, e.g.:

The colours were inspired by Prof. Mark Winter's website The Orbitron: violet had already been chosen for g (which matched), so I chose teal for h and orange for i. Double sharp (talk) 03:58, 17 March 2021 (UTC)
