I’m soon to be volunteering at a hospital nearby my university for several months and they require volunteers to wear clothing that identifies them in the hospital and I don’t believe any of the articles of clothing are of the colour blue.
I have autism spectrum disorder and a strange obsession with the colour blue and a phobia of other colours, so I would be unable to wear anything that is a colour other than blue or else I will not be able to function. I have a doctor(s) who has verified that my problem is indeed a valid medical problem.
How can I request to be accommodated for this without embarrassing myself or making a bad first impression with the staff there?
