yellowface is a very tricky trait to breed but the first thing to know is that type 1 and type 2 only describe the appearance (phenotype) of the bird and not its genetic makeup (genotype).There are actually 3 genes that can produce the yellowface trait. 2 of these are likely to produce the seafoam green you're looking for.
Any yellow on the body automaticly makes him a type 2. If he wasn't reccesive pied those areas would have appeared greenish.
Always Remember - Not every home needs a pet, but every pet needs a home. Please Breed Responsibly
