What is the coldest color?
Violet or blue-violet is said to be the coldest of colors, and the nearer to violet a color is located on the color wheel, the cooler . The color corresponds to frequency, which is a function of the amount of energy released.
What is the hottest colour of a star?
blue The colour provides a fundamental piece of data in stellar astrophysics—the surface temperature of the star. The hottest stars are blue and the coldest are red, contrary to the use of colours in art and in our daily experience.

What’s the coldest star color?
Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
Why is the coldest star red?
The dust scatters blue light more than red light, so stars appear redder than their true color. This effect is interstellar reddening.

How hot are green stars?
However, stars whose peak emission is green light (around 6000K, similar to the Sun) also emit a great deal of both red and blue light, and the human visual system interprets this mixture of colors as whitish rather than green.
Is there a purple star?
Although you can spot many colors of stars in the night sky, purple and green stars aren't seen because of the way humans perceive visible light. Stars are a multicolored bunch.
Is blue hotter than red?
When we talk about blue light being cool and red light being warm, we are referring to something very different from color temperature. We are using these colors to describe our perceptions or to convey moods. Counterintuitively, blue-hot is actually hotter than red-hot.
Are there pink stars?
The largest, R136a1, is approximately 260 times the Sun's mass; the light from these hot, new, bright stars is predominantly blue, however. At first glance, it's surprising, since there are no pink stars, and the majority of young starlight is preferentially blue.
Is there a green star?
Any star emitting mostly green will be putting out lots of red and blue as well, making the star look white. Changing the star's temperature will make it look orange, or yellow, or red, or blue, but you just can't get green. Our eyes simply won't see it that way. That's why there are no green stars.
Are there black stars?
A black star is created when matter compresses at a rate significantly less than the free fall velocity of a hypothetical particle falling to the center of its star, because quantum processes create vacuum polarization, which creates a form of degeneracy pressure, preventing spacetime (and the particles held within it) …
Is there purple fire?
The color of the flames is apart of temperature affected also by the type of fuel used (i.e. the material being burned) as some chemicals present in the material can taint flames by various colors. Blue-violet (purple) flames are one of the hottest visible parts of fire at more than 1400°C (2552°F).
