This is where I first encountered that study on blue in relation to Homer:
99% Invisible, another cool podcast which originally led me to that Homer podcast, has a segment concerning conceptual blueness and its representation in scifi which is also interesting. Their whole project is worth some time (if you’re interested at all in historical design or the potential futures of design and culture) – particularly their segments on revolving doors and the history of fire escapes and egress in urban design. (spoiler, they originally marketed little baskets attached to ropes for you to escape the fire out your window!)
If you’re interested at all in blue in art, definitely read up on Yves Klein.
Add your own blues in the comments!
