Loqiarchive in the context of the indieweb refers to date-grouped (often monthly) sets of posts (AKA personal historical archives, a common form of temporal navigation), but can sometimes mean archival copy, a copy of a web page made (often by someone other than the author) at a particular point in time https://indieweb.org/archive
petermolnar[chrisaldrich]: turn it into a math problem: derive the color from something like number of words on the post, or something more obscure (Zegnat chip in which ideas), etc., make a mini-theme-template, and populate it according to the color.
ZegnatI did that once. Most hash functions (should) have random distribution, and most can be hex encoded. So you can hash any of the blog content, and take any 6 symbols from the hex string at random to get a unique colour. The results were lackluster
rototoI think now social networks+messengers have totally won the competition. Some time ago admin of one FB group decided to move from FB and asked subscribers. Typical comment: anywhere but not a website!
