This is possible within SuperLab. I would suggest having the colors names that the participant is to click on being in one picture file. Within the picture file, make the words spaced out in such a way that makes it easier for you to define the areas.
Create an event with stimulus type [B]Picture File[/B]
Import the picture file that was created with the color names
To create on-screen responses, go to the [B]Experiment[/B] menu and then [B]Participant Input[/B]
Check[B] Mouse or Touch Screen[/B] as an input device
The [B]Participant Input Editor[/B] appears
Click on the[B] New [/B]button to create a response
The [B]Mouse Response Editor[/B] appears
Click on the third option that reads, "Specific area found at location (in pixels)"
Define the areas on screen where the participant will be clicking either Red, Green, Blue, Brown or Purple
After defining the five areas, one for each color word, click [B]Ok[/B] to exit
In the [B]Participant Input[/B] dialog, there is a [B]Preview[/B] button that will display in a blue border the areas that have defined responses
Go back to the picture event. In the [B]Event Editor[/B], under the [B]Stimulus[/B] tab, click the [B]Preview[/B] button. This will illustrate the five areas that were defined under [B]Participant Input[/B]
