pick a color -- 3

I am learning Unity and need someone to teach me 4 functions in a video. In the video please show your cursor. Also attach any scripts to your submission back to me. Thank you.

here is a link to the project https://www.icloud.com/iclouddrive/0d5-izBLXuxL_OB6LPtvbn-og#math08 There are 4 functions I need.

1
There is a scene named "colors". In the scene I have 2 sets of cubes. One set is blue and the other is red. Each set has a corresponding color picker. I want the user to be able to touch a color the left color picker and blue cubes turn that new color. Also, I want the user to be able to do the same for the red cubes with the right color picker. Lastly, I want the script to be able to change the the blue cubes in the scene "8p6".

There is a scene named "8p6". There is a 2d object named "1b". I would like the user to be able to drag 1b, but when the user lifts the mouse up, 1b returns to its original location.

3.
Also in scene "8p6". Right now the user is able to drag the "8b" into the "right10" 2d object and the "6b" into the "left10" 2d object. After the user puts "8b" and "6b" into it's correct grid, I would like the current scene to automatically advance to scene "8p6B" after 3 seconds.

4.
Also in scene "8p6", attach a click sound when the player succesfully puts the "8b" object into the "right10" object.
