Yes, the barred part is blue. Technically speaking a blue barred chicken is solid blue, just light vs darker blue. However a REALLY good barred bird would be white and blue striped instead of light vs darker blue.
If a chicken carries the blue gene it's got blue and thus qualifies as blue
I think the OP prefers seeing birds with more blue than other colors though
