Colors don't "move through the spectrum". Light of different colors has the same speed in a vacuum. In transparent materials such as glass or water, there are slight differences in speed, but that depends on the materal.
Light moves slowest through solids, as the particles are closely packed together and can absorb and re-emit the photons. This interaction causes light to slow down compared to its speed in a vacuum.
Gas because it has the farthest distributed particles which take time for them to contact one another. Energy transfers slower when the particles are mores spreadout.
Mechanical waves travel slowest in gases compared to liquids and solids because gases have a lower density and their particles are further apart. This means there are fewer collisions between particles, leading to a slower wave speed.
As an object moves away from an observer, the light from the object shifts towards the red end of the spectrum. This is known as redshift, and it occurs because the motion of the object causes the light waves to stretch out, which leads to longer wavelengths and a shift towards the red end of the spectrum.
Light travels slower in oil than in a vacuum because oil has a higher refractive index than a vacuum, which causes light to slow down as it moves through the medium. The denser the medium, the slower light will travel.

The highest frequency of visible light is violet.

The planet that has the slowest orbit would be Neptune due to the fact that is is furthest away from the sun. However, if you want to count dwarf planets, then Eris would be the slowest.
the one that moves the slowest
a donkey. she is a donkey because she moves at the slowest rate possible.
Sedna.
The slowest animal ever is the three toed sloth, which moves at a rate of only 100 yards per hour.
Pluto is the slowest planet to move around the sun, because of its far distance.
A Turtle is definetley the slowest animal because while a turtle moves it takes a very long time to move from places to place.
The speed of a star affects its spectrum through the Doppler effect. If a star is moving towards or away from us, the wavelengths of the light it emits will be shifted towards the blue (blue shift) or red (red shift) end of the spectrum, respectively. This shift can provide information about the star's velocity and direction of motion.
