Designating particle colors

Also, Start Color is planned to be deprecated on the next SDK update.

The Constant / Rand Two options on designating values is defined as follows:
Constant: Constant value Rand Two: Value moves randomly between the designated two values

Performance Instability
This feature is unstable on the current version's particle editor.
Creating another particle is recommended for using multiple particles.

On the current SDK version's editor, this feature is unusable due to technical issues.
As a substitute, setting "Render Setting / Render Mode" to Streched will create a pseudo-trail effect.

About Easing Type
On each features which includes Easing Type, an easing curve can be designated to determine its behavior.
As a reference, see Easing Functions Cheat Sheet for easing curve definition and examples.
