I am not sure how the rainbow drawings at the beginning of the pandemic started. The narrative in the UK seems to be that the rainbow is the NHS rainbow to support the country’s national health system and its workers. I am sure other countries have similar country-specific and country-centric explanations. The rainbow as a symbol for hope in pandemic times might have started in Italy, but I’m not 100% sure, so if you have more information, please let us know in the comments.
Our son couldn’t resist drawing a rainbow with his battered Lamy aquaplus watercolour set either. Stationery use is always encouraged!
You might know that England’s Northwest isn’t exactly the sunshine capital of the world, so I was quite surprised to see that into the middle of the Summer 2020 many rainbow pictures in windows were already rather faded. With the sun being so weak here I assume the many faded rainbows must be due to cheap supermarket-own-brand stationery that can be pretty awful. I don’t remember seeing any non-faded rainbows in the last months (except our Lamy one).
What I really like about the Lamy set is that each colour is individually replaceable, not that I will have much luck finding replacements in the UK, though… Yes, it’s € 5.90 while some no-name alternatives are only £1, but I think it’s so much better than the cheap watercolour sets!
