how can i change the colour of one 2d sprite based on collision of 2 other sprites?

using only one csharp script inside an empty object (if possible), in this code, how can i change the colour of one 2d sprite based on collision of 2 other sprites, in a simple example only doing that? and also (if posible), having the console logging all the resulting information? thanks in advance!

 

You need to detect a collision and be able to check wich sprite you collide
https://docs.unity3d.com/Manual/CollidersOverview.html
https://docs.unity3d.com/ru/current/ScriptReference/Collider2D.OnCollisionEnter2D.html

Then you need to get actual sprite renderer component
https://unity3d.com/ru/learn/tutorials/topics/scripting/getcomponent
https://docs.unity3d.com/ScriptReference/SpriteRenderer.html

And set desired color
https://docs.unity3d.com/ScriptReference/SpriteRenderer-color.html

 

thanks! trying to squeeze the code, should be something like this? (i didn't test yet...) https://etherpad.net/p/unityhowcngclr2dsprtbfromcoll2othrsprt

 

i'm struggling to go further than this (made on version 2019.3.0a12)
