Collision with pixel?

[Digitalic]

Is it possible for an active object to detect a collision with a pixel?

e.g. If I had a background image with various coloured pixels on it, could an active object detect when it collides with a specific colour of pixel in the background image?

Or, can an active object only detect collisions with another active object or backdrop?

You can only detect collision with objects, not colours, sorry.

Thanks for confirming that.
