I once had a spec job that wanted an odd color #10 THHN stranded. It was a 'special order' 10K feet minimum.
Client (engineer) said.." cost is no issue, follow the spec, and order it"
We used less then 200' total to one electronics rack, the balance went to their warehouse.
Ironically, when they went 'belly up', they gave it back to me. It was 'pink' or 'light red' and went to other jobs.
