Color League

Tweens, right click object> Add> Behavior> GENERAL> Tween, offers a wide variety of animatable properties. Those include position, size, opacity, and even color.

This tut will show you how to use the color filter to add a changing color effect to your project.

Again I'm using a Sprite made in an image editor with its color set to white.

After adding the object add the Tween Behavior.

Make sure its enabled.
Its is by default.

Then place the object where you want in the layout. It's over another Sprite in this example.

On to events. 

+ System: On start of layout

-> Sprite2: Tween "c0" property Color to rgb(51, 48, 228) in 2 seconds (Default, destroy: No, loop: No, ping pong: No, repeat count: 1)

-> Particles: Fast-forward 120 seconds

+ Sprite2: On Tween "c0" finished

-> Sprite2: Tween "c1" property Color to rgb(246, 55, 236) in 2 seconds (Default, destroy: No, loop: No, ping pong: No, repeat count: 1)

+ Sprite2: On Tween "c1" finished

-> Sprite2: Tween "c2" property Color to rgb(251, 180, 84) in 2 seconds (Default, destroy: No, loop: No, ping pong: No, repeat count: 1)

+ Sprite2: On Tween "c2" finished

-> Sprite2: Tween "c3" property Color to rgb(250, 234, 72) in 2 seconds (Default, destroy: No, loop: No, ping pong: No, repeat count: 1)

+ Sprite2: On Tween "c3" finished

-> Sprite2: Tween "c0" property Color to rgb(51, 48, 228) in 2 seconds (Default, destroy: No, loop: No, ping pong: No, repeat count: 1)

At the start of the layout make a custom tag named "c0" and choose the option to tween its color.

Tags allow us to reuse this tween, and even start new tweens as you see in the addition events after the start of layout.

As you can see this works as a chain of endless events changing from one color to the next, and back to the original using the "on finished" trigger.
