A mask overlay is displayed over protected areas to make it easy to differentiate between masked and unmasked areas. The mask overlay is a red-tinted, transparent sheet. If you adjust the transparency of a mask in certain areas, the degree of red displayed by the mask overlay in those areas varies accordingly.
When you paint or modify the mask, the mask overlay shows what is painted or changed.
You can hide or show a mask layer while you edit an image.
