No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
Planetary nebulae can vary in color, but they are typically seen as shades of green, blue, or red. These colors are produced by different gases in the nebula interacting with light from the central star.
There are actually a number of different techniques that are used to estimate the distances of various astronomical objects. You can study the spectrum of the light (or any electromagnetic emission) from that object, and determine how much of a Doppler red shift there is (it's almost always a red shift, very few objects are approaching the Earth) and since the general rate of expansion of the universe is known, we can determine from the size of the red shift how far away something is. If the nebula is associated with a Cepheid variable star, then from the rate of variation and the brightness of the star, we have another clue. And, if we observe the nebula at two different seasons of the year, when the Earth is at opposite sides of the solar system, we may be able to get some parallax for a geometrical calculation, but that depends upon how far away the nebula is; if it is extremely far away, we don't have enough parallax to do it.
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.

No
Blue Shift Inc. was created in 1995.
The opposite of the red shift is the purple shift.

Blue Shift Inc.'s population is 30.

Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..

Outside of our Local Group, no galaxy gives off light that exhibits a blue-shift. You most likely meant to say "red shift."
