I can combine each participant into a file by itself and generate a different color for each layer. The issue is that Mricron only allows 19 layers, which is not enough. I can combine all my images into one file, but because all the images are on one layer I can't generate multiple colors within a single layer.  I have a file open with 19 layers, is there anway to save the file as a single image with all the layers and different colors in tact. I would be more than happy to meet over zoom or over the phone if messaging does not work.
