generally speaking things appears the colors that they do because of two things, the way our eyes and brain perceive them and the way the object absorbs and reflects different wavelengths of the light spectrum. our minds interpret the light spectrum as the colors red, orange, yellow, green, blue indigo and violet and any combination of these colors. when light strikes an object, the object absorbs and reflects light waves, for instance if an object appears red to you, it's because the surface of the object absorbs all the other light wavelengths except red, which bounces back to our eye and causes the object to appear red. strangely enough, when all colors of the light spectrum are bounced back to us, we perceive the object to be white and when none of the colors are reflected, we perceive the object to be black!

∙ 15y ago"red" is the word we use to describe one portion of the spectrum of light which our eyes pick up. Basically, light has a lot of parts - called wavelengths - and every object reflects some light, and absorbs the rest. The bits that get reflected bounce off the object and into our eyes, so we see the reflected bits of light and call them colors. Stuff that we call "red" is stuff which absorbed everything but the "red" bits of the light.

∙ 13y agoThis is because white light is made up of all 7 colours of the rainbow. When the white light hits the red shirt, all colours except for red are absorbed so the red bounces back and reflects into our vision.

Where are cool red giant stars on the H-R?
Depending on the luminosity they will appear to the right of the HR diagram.
Why are stars yellow?
Some stars appear yellow because either they are yellow or the white color can appear different. The spectral types F and G (our sun), contain yellow stars. This is caused by their temperature.
What is the relationship between the color and temperate of stars?
The color of a star is directly related to its temperature. Hotter stars appear bluer, while cooler stars appear redder. This relationship follows a pattern known as the "temperature-color sequence," where stars of progressively higher temperature transition from red, to orange, to yellow, to white, and finally to blue. Therefore, star color can provide valuable information about their temperature and evolutionary stage.
Red-hot and blue-hot stars appear white to the eye because?
they are too dim to fire the cones
What is the past tense of some stars appear to be brighter than others?
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
Does the medium of space make distance stars appear to be more red shifted only because they are farther away?
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
What colors do Rigel and Beltergeuse stars appear to us?
Rigel: Blue-whiteBetelgeuse: Red
What are some examples of red stars?
nice q the answer is our sun is a red star and almost all suns witch are stars are red
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
What part of the modern H-R diagram do cool bright red stars appear?
top,right

Why are some stars are visible in march but not in September?
Because, e stars are in the sky in the same time of the year. In March, they appear high above the horizon, and in September they appear low.
What is up with red stars at night?
Most stars from that distance should appear white, those could be planes, copters, etc. Antares is a red super-giant star in Scorpio and is currently seen when looking south. To my eye it definitely looks red.
