The bear motif is apparently lifted from the city's coat of arms from 1780 (back when it was called Ust-Sysolsk). A bear also appeared in the Soviet-era coat of arms^[As far as I understand, in the USSR most city "coats of arms" were basically just tourist trinkets, unofficial designs used for pins and badges rather than actual official symbols of the city government.]. The bear is connected with Komi people's arctolatry of Osh, the bear in Komi mythology. Osh appears in this flag symbolically guarding the traditions of the Komi people, represented by the spruce tree symbol from traditional Komi embroidery. The bear itself appears to be drawn in a style influenced by traditional arts and handicrafts, I found a cool-looking painting by a Komi artist depicting a bear in a similar style, but then I looked into it and found out that that painting was apparently connected to a lot of really rancid far-right crap, so… woof. I originally attached that painting to this post but I edited it out now.

I also found this Permyak amulet with a strikingly similar bear design, the Permyaks being closely related to the Komi people, both speaking respective versions of the Komi language.

Going back to the Syktyvkar flag, there's also a sun symbol from Komi embroidery above the bear. The sun symbol is called "Shondi" or "Shondiban". Syktyvkar is a place where the sun can be visible for up to 19 hours at a time, so I guess that figures.
The blue, green, and white colors come from the flag of the Komi Republic itself, Syktyvkar being the republic's capital, as said; and the colors are intended to evoke 
AURORA BOREALIS. Which TBH kinda feels like it's overselling how northern the city is, like you don't see cities at the same latitude in other countries making a big deal out of how they very occasionally see the northern lights… But hey, I guess seeing northern lights at all, if only infrequently, is a pretty special thing, right?
So yeah. Cool flag. Main.
