Sorry to bother but my code looks perfectly right. I am trying to make the images random colors using the random integer block, but sometimes the color doesn’t even show up! It could be something else but I thing that the random integer is not generating the right numbers. This is the project. Thunkable P.S: My code was too long so I had to link the project, sorry 
The problem is that you have put in the raw block instead of a variable. Each time you call this block in your code, it will call multiple random numbers between 1-4. Set the random integer block in a variable, then replace the random block in your if statements with the variables.
