the star remains the same colour until it runs out of fuel and starts burning something else, and chnages size. then it will be a different colour.
were a star to be observed simultaneously from here and from new m'h'tn, what you ask would depend entirely on the relative positions and speeds of all three bodies. the relative motion of this hypothetical star would determine its doppler shift to blue (coming closer) or red (getting further away) but this would not actually affect the colour of the star (obviously) When a fire engine goes down your road, you hear its siren change tone as it gets closer, goes past you, then gets further away; but does the siren actually change? No its purely relative to speed and position. if earth, M'h'tn and the star in case are all moving at more or less the same speed in more or less the same direction then you don't even get much doppler no matter how far away it might be.
its relative speed would have to be **very high** for the effect to have clearly altered the stars visible spectrum, usually this is only noticed on very distant bodies moving at extremely high speeds e.g. quasars. So the answer is yeah it's still blue seen from either place, normally.

the answer is yes. mostly. the blueness of the ball is a characteristic of the makeup of the ball. it would appear the same colour on any planet UNLESS the immediate local light conditions were sufficient to alter its percieved appearance to us. if the planet you were on was close to a star of a very different colour then it would alter the apparent colouration of the ball, but the ball would still be blue. just like if you shine a coloured beam onto an object during daytime you change its colour but not by much unless its very intense.
stars of whatever colour (except the dead ones) emit white light no matter what colour they are, and espite their different colourations its actually a very pure white light. on an earth type planet a sensible distance away from its star all colours will be essentially the same as they are here, unless local conditions dictate differently (like there's some weird gas in the atmosphere)
blimey ME actually knowing something, gosh thats scary!

the color of an object is determined my what its made of, not by what color of light is shining on it. take a white piece of paper and put it under a red light. it'll look red, but the paper is still white.
the color you see is the wavelength of light that the object reflects. all other colors are absorbed by the object, and hence you don't see them. your blue ball reflects blue light and absorbs all other colors, a green blade of grass reflects green light, etc. a sheet of white paper reflects all visible light, while something black absorbs all colors and reflects none.

The other day, in study hall, i farted really loud, you know...so the guys would laugh...and i swear it was so hanus that Susie Johnson almost ralphed up her salsbury steak.
it was freakin sweet...
