Makes sense to me!  I'm "tint blind" -- not really a clinical term but 
describes what I see (and don't see) more accurately.  Depending on 
lighting conditions and how I'm processing colours black, a darker navy 
blue and dark brown could all look the same.  I use "known blacks" to 
help distinguish: I know the telephone is black or when I was working at
the store my pants were black so would compare the unknown item to the 
known black.  If was black then would stay being seen as black, 
otherwise then I could tell was navy or brown.

As for your boss using those wild colours on the bar graphs, makes sense
to me!   There are times when a light red and a dark orange will look 
the same to me.  I've also found a skinny coloured line isn't enough to 
'trigger' knowing what colour it is: yup, it's a colour!  Same a little
bit larger (such as scroll_enlarge) and "oh! that one is 'red' and that 
one is 'orange'!".

And you may have read elsewhere I do electronics as a hobby -- my spare 
resistors are in coin envelopes to sort as the coffee can of parts - ha!
