It reminds me about the colour yellow in rose symbolism: They give a message of appreciation and love without the romantic notion of red roses. These flowers are a good bunch to give to your friends and family for well-wishers of health and speedy recovery, or to simply show your appreciation.
I read this very detailed article on the history of the colour yellow
, and how we can use it in practical ways in our art-making. That's where I learned this fun fact from!
