We now have a Discord server, come talk to us!
- April 21st: Please don't use the 48h FFD reason if you wish to flag your own upload as an inferior version to something else. The custom reason is only there for the rare occasion that an upload needs to be deleted permanently, not just replaced with a better/different version.
- February 26th: Ratte has removed a ton of old records recently. If you see you've been getting a record "again" please check first that it doesn't say the record has been removed or updated. If the subject uses either of those words your record was either deleted or has been downgraded from a negative to a neutral.
- Missed the update about decaying records? Check here for details.

Many are, but they aren't true color. The sun is approximately (and it's a pretty good approximation) a black-body emitter, and it's emissions peak in the green part of the spectrum. A black body radiating strongly in the green is also radiating strongly in the rest of the visual spectrum, so it ends up looking white (a faintly yellowish white, but if you saw it directly (through a good neutral-density filter, hopefully!) you'd call it white).
Also the claim that the Sun is classified as an orange dwarf is a new one to me. I was taught (and every source that I can find sides with me on this) that the Sun is a G dwarf ("yellow dwarf"), not a K dwarf ("orange dwarf").
