This black t-shirt features a unique design inspired by the Ishihara color blindness test. The print showcases five circular patterns, each designed with color variations, accompanied by corresponding text labels: Drink Water, Sleep, Shower, Eat, and Make Noise. The playful message suggests that if you can't see the 'number' within the circles, you might need these basic essentials. This tee is perfect for anyone with a sense of humor, especially those interested in vision science or color perception. Ideal for casual wear, it's a conversation starter and a fun way to express your personality.
