It's not a bad idea to standardize distinct COLOR, SHAPE, and ICON of different Bitcoin unit 'logos' (milli, micro, nano, pico would need to be quite prominent). If client designers want to express number in those colors, I think that's at best secondary.
Yeah.. for some reasonably loose definition of 'standardize' that still gives artists reasonable freedom.
I'd say it's more of a 'guideline' and I'd only push for it as a standard in so far as saying 'please don't use green for millicoins if 99% of the planet is using green for microcoins'
Agreed - the colouring of the number itself is secondary.
EDIT: As dictator for the day (who has suffered through a dozen such discussions over the year), I declare the 'cent' discussion closed and buried. SI units of three (10^n3) are the only reasonable way to go: giga, mega, kilo, milli, micro, nano, pico (no deka, deci, centi, nor hexisepticenti). Satoshis (10^-8) may survive as a charming oversight.
I've followed a few discussions around this myself.. and while I've disagreed that bitcents should disappear, my argument has mainly been that I expect the general public will expect them to exist, and will use the concept anyway.
However.. in the interests of simplicity, why not give them a chance to die out and see what happens?
so.. If you check back in my edited original post, I've ditched the bitcents and produced a simplified chart.
Thanks to everyone for the feedback.
Perhaps this whole thread has been just yet more noise on the units topic and will be ignored anyway.. but one day something like this will stick and gain wider traction I hope.
