HTML hex color questions

Question

As a graphic designer, there's one thing that bothers me:
There's a question on the HTML quiz that says "Which color represents the hex value #0face0?"
The "correct" option is blue. The problem here is that that is misleading, blue #e0 value ADDS green #ac value, doesn't OVERRIDES it, as the question suggests. Therefore, the correct option would be something more like a cyan(ish), not blue.
I think that might be important to address that issue, given the fact that people are in sololearn for learning...

Answer 1

Maybe blue is just closer than other options. But in general you are right, I'd think it's rather cyan.

Answer 2

@Petr yes, that's true. The other options just doesn't make any sense, so this question is rather easy to answer. Nevertheless, I think there's a trend to use the hex colors in the same way, taking in account just the bigger value, not the sum of the three, and I wanted to give my two cents to tackle that problem.
Thanks for taking the time to answer, btw!
