I generated a path with https://www.tldraw.com/ and then recolored it. It’s drawn twice, once with a rainbow gradient (see svg filter #gradient in the source) and once with sparkles (see svg filter #noise in the source).
Sponsorship should unlock premium colors, so that you can tell from a screenshot whether they’re a free user or someone giving you money
What I’d really like is access to HDR brightness, so that the sparkles could be >100% brightness. Safari has support for wide gamut, but not HDR brightness, as far as I can tell, unless you use this trick.
