The color of a star is closely related to its temperature. Cooler stars appear reddish in color, while hotter stars appear blue. This is due to the relationship between temperature and the peak wavelength of light emitted by the star.
The temperature of a star can be determined most directly from its color. Hotter stars appear blue or white, while cooler stars appear red. This relationship is known as Wien's law.
Cassiopeia is a constellation in the night sky, not a single star. The stars in the constellation vary in color and surface temperature. Some may be blue or white-hot, while others may appear red or orange.
Blue. :D
The color black makes blue darker. Infact it makes any color darker.
A star with a surface temperature above 30,000 degrees Kelvin would appear blue in color. The color of a star is directly related to its temperature, with hotter stars emitting more energy in the blue and ultraviolet parts of the spectrum.
A star's color in the Hertzsprung-Russell diagram is determined by its surface temperature. Hotter stars appear blue or white, while cooler stars appear red.
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.
Blue
the suns colour is white, allthough from the surface of the earth it may appear yellow because of atmospheric scattering of blue light.
In general open expanses of water reflect whatever colour is predominant in the environment. This usually tends to be the sky colour. If the sky is clear, water in the sea or lakes will appear blue. If the sky is dull, so also will be the water surface. The tap water in the glass will still usually be clear.
It is a blue colour, then clear, then blue. it is stripy.
Blue color does not appear in starch solution titration because the blue color change is specific to the iodine-starch complex. In the presence of iodine, starch forms a dark blue complex, masking the original color of the solution. This is why the absence of blue color indicates the endpoint of the titration.
they appear blue due to the flame
blue
His eye color is a dark brown.
The first thing you notice on a clear day is likely the blue sky. Clear days typically have a vibrant, deep blue color due to the scattering of sunlight by the atmosphere, which makes the sky appear cloudless and bright.
