Speed Force

"The Speed...Nora here...is omnipotent, omnipresent, and omniscient."

- Chester on the Speed Force

The Speed Force was a source of energy that provided speedsters with their powers.

Creation
The Speed Force itself was created at the beginning of time and will never die as it is an infinite amount of energy. During the history of the Multiverse, Speed Force has given countless Meta-Humans with its energy and turned them into Speedsters under different circumstances.

"Death"
During the Crisis. The Spectre gave Barry Allen a boost to enter the Speed Force in order to travel to the Dawn of Time. After the Multiverse got restored, Wally West felt something wrong and returned to Central City to talk to Barry, only to know that he suffered from a few "hiccups" while accessing his speed. Later, they entered the Speed Force to talk to them and realize that the Spectre energy unbalanced the nature of the Speed Force and caused its "death". After the death, Barry and the other speedsters started to lose their speed which caused Barry to begin to build an artificial Speed Force.

"Resurrection"
Despite Barry's creation of the Artificial Speed Force, it inhibited his emotions and hurt Iris. This caused Barry to regain his emotions and destroyed the ASF with a lightning bolt. However, Barry required his speed to fight Mirror Monarch and was able to restart the Speed Force with the energy residue in Iris' body after years of contact with Barry's super speed. Unbeknownst to Team Flash, the reactivation created the Strength, Sage and Still Force.

Asking for Help
After being allegedly attacked by the other Forces, the Speed Force was severely injured and teleported to S.T.A.R. Labs as Nora Allen, seeking Barry's protection. The team then brought her to the medical lab and treated her injuries. However, the Speed Force being weak caused Barry to have a slower speed and forced him to enter the Cryo Pod.

Under protection of Barry, "Nora" worked with him as a crime scene investigator and attempted to help him with random bursts of energy. This enraged Barry and he told her to leave. Iris then approached "Nora" and talked to her about how Barry felt uncomfortable with the Speed Force as his mother. The Speed Force later reconciled with Barry and agreed to work together to protect her.

Going Rogue
"I need your powers to defeat her, and you promised. And now you're breaking that promise. And I know why. You may be his lightning rod...but I'm the lightning."

- "Nora" attacks Iris

After frightening Alexa Rivera, "Nora" attempted to kill Iris in order to gain Barry's support. Barry leaped in front of the lightning and counteracted it with his own bolt. "Nora" stopped the lightning bolt midair and absorbed into her own, eventually blasting Alexa with double lightning bolts and killing her.

Yellow and orange
Yellow lightning is seen on Speedsters who recently gained a connection to the Speed Force and their power has not yet manifested. However, Speedsters wearing a reflective armors will emit white lightning. As the speedsters gain more power and a stronger connection to the Speed Force, their lightning will be manifested into orange. The following are the speedsters who emit yellow and orange lightning:

Red

Red lightning is seen on Speedsters with a connection to the Negative Speed Force. It is also seen on Hunter Zolomon who became Black Flash after being taken by Time Wraiths. Edward Clariss also had red lightning due to an unknown reason. The following are the speedsters who emit red lightning:

Blue
Blue lightning is seen on speedsters who gained an artificial connection to the Speed Force, mostly the use of Velocity Serums. After mixing with Tachyons, the blue lightning will turn into white and will occasionally emit blue lightning. The following are the speedsters who emit blue lightning:

White
White lightning is seen on speedsters who used Velocity Serums and Tachyons to increase their speed. White lightning is also seen on speedsters who uses reflective armors. However, white lightning was never recorded in history books and in the database of Flash Museum. The following are the speedsters who emit white lightning:
 * Godspeed Clones
 * Godspeed Clones
 * Godspeed Clones
 * Godspeed Clones

Purple
Purple lightning is seen on Accelerated Man and briefly Iris West-Allen after Matthew Kim transferred Barry's powers to her. Their are currently no explanation for why purple lightning was created while running. The following are the speedsters who emit purple lightning:

Yellow and purple
Yellow and purple lightning is only seen on Nora West-Allen. It is presumed that the mixed color lightning is caused by genetics as her mother (powers briefly transferred to her) and father emit purple and yellow lightning respectively.

Red and purple

 * For further information, see Negative Speed Force.

Red and purple lightning is seen when Nora gained a connection to the Negative Speed Force.

White and yellow
White and yellow lightning is seen in the Speed Force when a physical form of Speed Force tried to regain Barry's body and save him.

Black
Black lightning was seen when a speedster got infected by Ramsey Rosso's blood.

Green
Green lightning is seen after Speed Force was unbalanced by Spectre energy.

Eye
Having connection to the Speed Force allows the speedsters to have lightning flicker or glow in their eyes. The color of the eye is nearly identical as their lightning color with an exception of Hunter Zolomon as he have black glowing eyes and blue lightning.
