I want to customize my thumbnail in portfolio grid. Right now, when hover, the thumbnails will turn into black screen with text on top. I want to change it to, before hover, the thumbnails are Grayscale (BnW), then when hover, they will turn to the original image with text on top.

Please help me and thank you so much!
