Rainbow
A rainbow is a bridge of fortune and the reward at the end of hardship. Seeing one after the rain clears means worries lifting and a happy occasion coming, and it often appears as hard work finishes. Crossing a rainbow or passing beneath it means moving into a different stage. But a rainbow soon fades, so it was also read as a reminder that good fortune will not last — settle things while it is here.
A rainbow cannot be walked to: step toward it and it withdraws by exactly as much. Traditional reading saw it as a bridge joining sky and earth and handled it as a symbol of celebration and reconciliation. The clearer it is, the better it reads.
Readings by Situation
Seeing a clear rainbow
A good sign that worry lifts and something to celebrate arrives. Vivid colour reads more strongly. If things have been hard for a long time, take it as a sign you are at the tail end.
Crossing a rainbow or walking towards one
A sign of moving to the place you hoped for. Tradition read the rainbow as a bridge and handled it as a symbol of joining. If a tie has gone distant, read it as a time when it eases.
A rainbow fading quickly
A sign that a good stretch passes briefly. Rather than a bad omen, take it as a call not to miss the moment. If there is something you can take hold of now, do not put it off.
A faint or half-formed rainbow
A sign that the finishing is still ahead. Read it as something roughly halfway. Taking it as a nudge to push a little further is fair enough.
Tradition handles the rainbow as an auspicious symbol. Its fading quickly is no reason to call it a bad omen. Even so, do not decide on a large expense because of it.
