Explication
Some adjectives change meaning depending on whether they go with ser (an inherent trait) or estar (a state or a result of change). The headline pairs: es aburrido 'is boring' / está aburrido 'is bored'; es listo 'is clever' / está listo 'is ready'; es rico 'is rich' / está rico 'is tasty'; es verde 'is green' / está verde 'is unripe'.
The logic is consistent: ser classifies — it tells you what something is like by nature — while estar reports how something is right now or how it ended up. More pairs to know: vivo (ser 'sharp/lively' / estar 'alive'), orgulloso, atento, and abierto ('open-minded' as a trait vs 'open' as a state).
Estar + adjective also frames a present impression — how something looks, tastes, or feels at the moment: ¡qué linda estás hoy! comments on this moment, whereas eres linda states a permanent trait. The same adjective, two truths.
