Aryan: We learnt how to create stories in previous chapters of Scratch. But I
have seen so many videos in the tutorial menu. Colors and sizes of the sprite were
also changing. Please tell me how we can do that. I also want to learn it.

Gowri: Yes dear. Colors and sizes of sprites can also be changed. Let’s learn today by
5 different options of “Looks” block and different activities related to it. These are
as follows.

8.1 CHANGING SIZE AND COLORS— “LOOKS” BLOCK

All these blocks are “stack” block.

8.1.1 “change size by…” block

This block is used to increase or decrease the size of the sprite.

8.1.2 “set size to…” block

This block is used to set the size of a sprite to a specific size, which you want.

8.1.3 “change color effect by…” block

This block is used to change the color of the sprite by changing the color code by
any value.
