Those buds look perfectly fine, you just have to be patient. It seems like once they bud it takes them forever to open; but when they do, it's well worth the wait! Send pics when they start to open...love to see. I love the harlequin/spotted types!
This is bud blast on a Phal. As the others have said yours is very healthy. Unfortunately, all of the buds on this plant blasted and this is the last one hanging on. You can always tell when a bud has blasted because in changes color and becomes very soft.
