when green flag clicked
set [color v] effect to ((1) / (0))


Well, it doesn't work anymore… Somebody on the Scratch Team… PLZ FIX THIS!

You mean greyscale? There's an alternative way by layering 2 sprites together to form grey,

- First sprite has to create a clone, and to back layer.

- The clone sprite goes in front, has to match the first sprite costume, using ghost effect of 50, and set color effect to 100

when green flag clicked
go to [back v] layer
create clone of (myself v)
when i start as a clone
go to [front v] layer
set [color v] effect to (100)
set [ghost v] effect to (50)

Also, another thing I have heard about is that the set color to 1/0 method does not work on all devices. Though it does seem to work on PC's.

it's supposed to be
set [color v] effect to ((-1) / (0))
it still works, you just put 1 instead of -1

That is still the same as
set [color v] effect to ((1) / (0))

Hey, that actually works! I'm using Chrome OS and the original 1/0 method had worked in the past… Thank you for the alternative!
