Issue description

Hello,

I want to tween the color of a cc.Sprite with this line:

`    tween(this.sprite1).to(3, { color:Color.TRANSPARENT }).start();`

But the color property is not present.

Regarding this post, this bug should be fixed in CocosCretor 3.6
https://discuss.cocos2d-x.org/t/fade-in-and-out/55902/2

But I got this problem with CocosCreator 3.6.1.

I need to add UIOpacity component to change the opacity property.

tween(this.sprite1.getComponent(UIOpacity)).to(1, { opacity:0 }).start();

Relevant error log output

No response

Steps to reproduce

Add a Sprite component then try to tween the color.
tween(this.sprite1).to(3, { color:Color.TRANSPARENT }).start();

@BenoitFreslon Cocos Creator uses Entity Component architecture. So Node is an entity without any rendering relative functionality. So you can't tween color property on Node since it doesn't exist on Node.

I misunderstand the issue.
The issue is to create a tween color for sprite component, it is not relative to color property on Node. I will fix this issue soon.

[BenoitFreslon]

Yes it is.
If I remeber the old documentation shows an example with a tween to change the color sprite. That's why I posted this.
Thanks.
