The Enabled property, much like ParticleEmitter.Enabled, determines whether sparkle particles are emit. Any particles already emit will continue to render until their lifetime expires. This property is useful for keeping pre-made sparkle effects off until they are needed later. Since sparkle particles are destroyed when the Sparkle object's Instance.Parent is set to nil, this property is useful in allowing existing particles the opportunity to expire before destroying the Fire object altogether. See the function below.

local Debris = game:GetService("Debris")
local part = script.Parent
function stopSparkling(sparkles)
	sparkles.Enabled = false -- No more new particles
	Debris:AddItem(sparkles, 4) -- Remove the object after a delay (after existing particles have expired)
end
stopSparkling(part.Sparkles)

This property functions identically to Sparkles.Color.

The SparkleColor property determines the color of all the particles emit by a Sparkles object (both existing and future particles). It behaves similarly to ParticleEmitter.Color, except that it is only one color and not a ColorSequence. Sparkles have a natural color sequence applied which is most apparent when this property is set to white; sparkles very faintly animate between a subtle green and red.

It should be noted that sparkles have a partial ParticleEmitter.LightEmission effect, so dark colors tend to render more transparent and white colors look very bright.
