We love a rainbow. And it’s no wonder really, that a rainbow is the symbol for so many things.

Rainbows are pretty rare and undeniably beautiful. As far as heavenly natural phenomenon go, they have inspired songs, books, legends, and artwork since humans…well…became humans. And it's image has evoked awe, delight, faith, and even controversy...

A brief look at Rainbow Symbolism

NHS Hope

The rainbow was adopted during the Coronavirus pandemic as a sign of solidarity for NHS workers, who were (and still are) on the front line of the fight against the virus. A nurse started the trend because she wanted to create a positive sign of hope for staff in hospitals across the country during the darkest days of the pandemic…and it really took hold in the public’s imagination. Windows across the nation were adorned with hand-coloured rainbows in all sorts of shapes and sizes. And along with the clap for carers throughout 2020, it has become the most recognised emblem of the crisis.

And at Bombus we support the NHS and our nurses whole heartedly. We have family, friends, and colleagues who either work for or have strong ties with to NHS, and we are 100% behind the campaign to ensure that our nurses are paid a fair and reasonable wage. And they are nothing short of heroic. If you agree and want to help, visit the change.org petition and add your name.

Is the use of the rainbow in this way at all controversial?

But the use as a symbol of the NHS during coronavirus wasn't necessarily welcomed by all. A number of members of the LGBTQ+ community that were uneasy about a symbol that had been theirs for over 40 years being diverted to another cause. Kirsty Conway puts forth an excellent and fair point in this article, explaining why many felt taken aback by its use.

Rainbow Babies

A rainbow baby "is a baby born after a miscarriage, stillborn, or neonatal death," as described by Jennifer Kulp-Makarov, M.D., FACOG,. "It is called a rainbow baby because it is like a rainbow after a storm: something beautiful after something scary and dark." She adds, "It is an extremely emotional and devastating experience to lose a pregnancy [or baby]. To create a life or bring a baby into the world after such a loss is amazing like a miracle for these parents."

Recently, a number of high profile celebrities and influencers have highlighted the importance of talking about miscarriage and loss.
