Vjeko Jelcic. Have you been found colour blind using the book of dots??
If so have you tried the lantern test.
On your class 1 medical, if you fail the book you will be given the latern test.
This happened to me, I am very slightly colour blind. But I still have a class one medical and ATPL (A) and ATPL (H).
So if you have not tried the lantern test have a go or find a consultant optician who may be able to help you.
Happy New Year.
