do you know anyone with colorblindness?

Yes, we had a co-worker who was colorblind. It is very strange and unfortunate thing that can happen to a human being

really interesting. did you witness/experience anything with them that affected their daily living negatively? 
1_Wizard
Not really. He was behaving normally as he would. By the way, are you knowledgeable about brain disease called dementia

that's always nice to hear! & I mean...I'm not an expert but I knew a thing or two about it. Why do you bring it up?
1_Wizard
I was just curious if you had encountered anybody with such disease in your life? And how those people typically behave overall?
