Revamp colors for promises based on status and time to deadline

[dreeves]

Here's an off-the-cuff proposal -- help with filling in actual hex codes solicited!

1. No due date -- obnoxious neon yellow
2. Overdue -- neon pink [1]
3. Due in <24h -- bright red
4. Due in <2d -- orange
5. Due in <3d -- blue
6. Due in >=3d -- green
7. Due in >=7d -- darker green
8. Completed -- black
9. Failed (cf Uncle button AKA "mark as failed" #248) -- dark red, almost black
10. Newly created -- gray [2]

Footnotes

[1] Or show little flames or sirens or something? Blinking would be too much but some kind of subtler animation somehow? Actually the realtime ticking down of the score may be exactly the ticket. And maybe that's the answer for no due date: a blinking "N/A" for the score to goad you into picking a due date to make the godawful blinking stop. :)

[2] This would be moot if we drop create-on-GET but I don't like making the promise gray like in the status quo. Instead, the background of the whole webpage should be a different color or something. Just some unimportant but obvious difference to indicate that the promise has been created.

@dreeves i wonder if we should use relative percentages of the time between tini and tdue rather than absolute days... thoughts?

Smart. I don't think I have strong feeling about this. If it's easy and you think that would be a more helpful color scheme I'm game to try it. But in practice it might turn out that the consistency of like "blue = 2 days" is what's most helpful. I'm imagining a user being all "why is this one green when it's due in a few hours and this one's red when it's due next week?" It could seem buggy unless we think of a way to make it more clear which maybe means some indication of what fraction of the way to the deadline we are, which... is either a good idea regardless or is taking us down a rabbit hole, I'm not sure which...

Vaguely related idea: A table layout where you can sort by any field you want. Default sort could be urgency (status quo) but you could also sort by time to deadline (absolute or relative), promise title, creation date, score, etc.
