How close are these two colors to being the same, If I bought a tour pack in cobalt blue and put it in a bike that is sinister blue would it be close to the same color??

 

Cobalt blue has a lot more red in it. It really comes out in subdued lighting, looks almost purple. I don't think you would be happy.

 

My bike in my sig is Sinister blue. No way it looks close to Colbalt blue.

Definitely not.
