Would this work? It doesn't seem to…

It's casting the boolean (true/false) to a number (1/0) and then interpreting that number as a color (really dark red/black). So it might work, but it's probably not what you intended to do.

So the <touching {\/}?> sensor doesn't produce an Boolean, but a colour value?
BTW, would there be a workaround for this?

Wouldn't <<color () is touching (color of sprite)> and <touching (sprite)>> work?

<touching ()> produces a boolean value, but <color () is touching ()> expects a color value so it tries to turn the boolean into a color value.

Ah, thanks.
