Why is the idea of a universal color wheel not appropriate?

A universal color wheel may not be appropriate because color perception can vary between cultures and individuals. Different cultures may have different associations and meanings for colors, leading to potential discrepancies in how colors are perceived and categorized. Additionally, individual differences in color perception, such as color blindness, can further complicate the idea of a universal color wheel.

What happens when bromthymol blue is exposed to CO2?

Why does the color of a star determine?

The color of a star is determined by its temperature, with hotter stars appearing blue and cooler stars appearing red. This is due to the relationship between temperature and the peak wavelength of light emitted, known as Wien's Law. It is easier to observe a star's color than its temperature directly, making color a useful indicator for astronomers.
