Whenever there is a relative motion between a source of light and observer then frequency appears to get changed. So colour would be changed. If both recede away from one another then there will be a apparent decrease in frequency and so colour has to move towards red end of visible spectrum. This is known as RED SHIFT

When was The Red Shift created?
The Red Shift was created in 2005-06.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Does a red shift indicates that objects are moving toward earth?
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
Can a red shift and a blue shift exist on the same object at the same time?
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.
Which astronomer discovered the red shift?
The first astronomer to discover that a galaxies red-shift was larger the further away it was was Edwin Hubble in the 1920s.The first scientist to describe red-shift in stars was actually Hippolyte Fizeau in 1848, though he was a physicist and not an astronomer.That light should be effected in this way was suspected by Christian Doppler (after whom "The Doppler Effect" is named) as early as 1842.
When a source of light approaches an observer the light appears to be than it actually is?
Blue shifted and when it is moving away it is under a red shift.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
Why does a red shift occur?
A red shift occurs when the wavelength of light emitted by an object is stretched, making it appear more red than it actually is. This phenomenon typically happens when objects in space, such as galaxies, move away from us due to the expansion of the universe. The greater the distance and speed of the object, the more pronounced the red shift. It serves as crucial evidence for the Big Bang theory and helps astronomers measure the universe's expansion rate.
What does red shift show?
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
