I have a peculiar question, which might be about the compounds of platinum and palladium.
In financial markets charts, numerical graphics, are generally a mess. There is no consistency of representation. For decades I have used some standard symbols of my devising: USD is always a black 5/2 star; GBP a red diagonal cross; JPY a red circle; etc. I’m extending the list (there are about a hundred such markers), re-coding it in SVG, and when ready will open-source it under a generous licence.
The extension should include the precious metals, in their capacity as traded sort-of money. XAU and and XAG have obvious colours, and shapes of ingots in ratios determined by the Good Delivery rules. XPT and XPD must be different. Alas their colours are, for these purposes, too close to silver. I need a non-arbitrary colour for each.
Maybe that should be the colours of their florides. Or of any other compound of them which have colours distinct from each other and distinct from Au and Ag.
(Of course, I am open to a different rule by which to assign two colours, especially if all the Pt and Pd compounds are white or gold-brownish.)
And thank you for reading thus far through an unusual question.
