[open] Spectrum image, from what participants can choose colors. It is possible?
I need to design an experiment, in that participants could choose a color from a spectrum of colors image. I need something like in photoshop (when you choose what colour to use), and that the color of that region where is mouse pointer to be seen in a square on the bottom corner of the display, and that colour need to be registered after normal mouse click on the choosed color.
Is possible to do something like this in OpenSesame?
PS: Sorry if my description is not so clear...
