How to Make Color Sequence with Code for Particle Effect?

I want to create a particle effect that has a color sequence with Instance.new(); however, I don't know how to set and write out a color sequence.

Like So:

local P = Instance.new('ParticleEmitter')
P.Color = ColorSequence.new(Color3.fromRGB(0,0,0), Color3.fromRGB(0,0,0))

Now you can modify how you get the colors like by using BrickColor or HSV up to you.
