The color of Sheldon’s T-shirt conceals five emotions that viewers haven’t picked up on yet but after reading this article they will soon.
Leonard loves to wear an undone button-down shirt over his polos, whereas Raj prefers to wear a cardigan, and Howard favors turtlenecks. When it comes to attire on The Big Bang Theory, there is strict adherence to continuity. In this sense, Sheldon is the same as everyone else, and most of the time, you can find him wearing a t-shirt with short sleeves layered over a shirt with long sleeves that has the sleeves rolled up.

Wears the Red Color when he’s angry

Orange when he’s greedy

Yellow when he’s afraid

Blue when he’s hopeful
Blue when he’s hopeful
Purple when he’s in love
Purple when he’s in love
Indigo when being compassionate
Indigo when being compassionate
Green when his willpower is strong.
