If you spend $100 on a black Thomson seatpost and $100 on a black Thomson stem....and one is a dull-ish dark gray/black and other deep glossy black (obviously don't match), you would probably have a few questions.

I can see it being ridiculous if someone expects the light green Cinelli bar tape to perfectly match their Bianchi brand Celeste saddle...but we're talking same company/same material (alloy).
Just figured there would be better consistency.
