Drag and Drop: Matching with Graphics (Many to Many Wizard)
This drag and drop uses three drag images (blue, orange and yellow squares) and one target image (red). Run your cursor over each image to see whether it is a drag or target image. The exercises also uses a violet square that is swapped (exchanged) with the blue square when the blue square is dropped on the red square.
What color do you mix with red to get violet? Drag the color on the left to the red block.
