Candle
Floorboards, animals and lost keys — the least glamorous candle, and quietly the most used.
These are associations the community holds, not settled fact — the more a reading is shared, the bolder it sits.
Brown gets left out of a lot of colour tables, which says more about the tables than the colour. Where it does appear it is given to the home, to stability, to animals, to practical matters and to finding lost things — and those are, by volume, most of what people actually want help with.
The planetary assignment varies. Saturn is common, for the earthbound and enduring qualities; some modern lists give it to the Earth itself, which is a twentieth-century addition that the older schemes had no room for. Either way the character is the same: slow, heavy, unspectacular and hard to shift once it has settled.
Practitioners use it for household protection that is meant to last, for animals and their health, for anything to do with property, and for the small persistent business of keeping a life running. Brown work rarely produces a story worth telling, which is arguably the recommendation. White substitutes; green where the point is growth rather than stability.
Readings practitioners have offered, ordered by how many recognise them. Take what serves, leave the rest.
Carried forward
Common in contemporary practice
Lit while actually searching for the lost thing rather than instead of searching. Practitioners who work this way describe the candle as a way of settling down enough to look properly, and are largely unbothered by whether that counts.
Credit what you carry. Much of this comes from living traditions, and some of it from traditions that are closed — held by particular peoples and not offered for general use. Where you know whose practice a reading came from, name them; where you don't, say that too.
