overused doesn't mean bad.

And my dad's color blind but it only affects blue and green or something like that.

overused means plain boring. unoriginal. uncreative.
but hey if you like it, it's okay

and your dad then is just blind for blue and green (if that's right, usually you say red and green because that appears quite often).
color blindness can affect every colour others distinguish, you could even see black and white only.

and yeah, gavel's right. you dont need to excuse... dont post it if youre aware of what crit's going to come...
