Foghorn - I am one of those !
I can't pass the test where you have to read the numbers out of the book as I am borderline colour blind. Its all a messy blur to me!
However when I did my original medical down at Gatwick (about 8 years ago), I obviously failed the book check but then passed the lanterns. So depending on the severity (it never changes through your life), you could be ok!
Anyway, off to get ready for work. Think I will wear my yellow / orange / blue combo as I think it looks nice!
