You need to target the specific images where you want the effect.

/* image block hover effect, uses LESS syntax */

#block-4669dfb9a780254b9b6d, // optional image comment here
#block-52b8e172d1875e9d06a0, // optional image comment here

  {
  
    filter : grayscale( 100% );
    transition : filter 0.3s ease-in-out;
    
    &:hover {
    
      filter : grayscale( 0% );
      
      }
      
    }

To find block ids check out Heather Tovey's most excellent looking Squarespace ID Finder.
