Because,Blue is the hottest light/fire and Red is the less hottest light/fire the bluer the fire/light the hotter it is,The redder it gets,the less hotter it gets from the temperature.
The color of light is related to its frequency or wavelength.
You see the color black.
Blue. That's why people call it a "blue surface" ... because any other color of light that hits it is absorbed, and never scattered or reflected to your eye.
When green light is shined onto a blue surface the color that reflects back into your eye is a dark Greeny Brown this is because all of the other colours of the spectrum are absorbed.
As light passes over it during the course of a day, an object sitting in a stable place changes its color. That's because color is a quality of light as it is reflected from the surface of the object and into the eye.
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
The surface temperature can be estimated quite precisely from the color of the light. The temperature of the core can't be measured as directly, and must be estimated based on our knowledge of how stars work.
How does the angle of light affect the temperature of a surface?
The red colour means that it's surface temperature is cool < 3,700K. At that temperature, the spectrum of light is red.
The color of light is related to its frequency or wavelength.
They are not related
Color temperature refers to how light is measured. Each color in the spectrum has a different light temperature. This fact has ramifications for both artists and scientists.
Neither of those things. Only the color of the light before it even reaches the reflecting surface.
Any light that bounces off of the surface is the same color as it was when it hit the surface.
Wavelength, or alternatively its frequency.
When you see the color red, you are seeing red light reflect off of a surface. This means that any other color light that hits that object is absorbed into the surface. The exception to this is when you see red light, in that case you are seeing light that does not contain any other color of light.
You see the color black.
