is it possible To Do This

Sorry For My Bad English

When you say 'everything' do you mean the background as well?

Sprites are easy enough (technically), but the background is a whole different thing. If you had a tree as a solid, would you want the ground behind the tree to be grey? If so, I would expect that would be beyond capabilities.

It might help if you show on your screen shot what you would like to see in detail.

YES I WANT SPRITES AND BACKGROUND BE GRAY,LIKE THAT IMAGE I POSTED

IS THERE A WAY TO DO THIS WITH EFFECT?

You did it again!

Quit typing in ALL CAPS! Not sure if you're new to the internet, but this is considered "shouting" and is very rude.
