<human>:  Could a dichromat probably easily distinguish chlorine gas from neon gas?
<bot>: No, a dichromat probably could not easily distinguish chlorine gas from neon gas. A dichromat is someone with color blindness that can have difficulty distinguishing red and green. Chlorine gas is green or yellow-green. Neon gas is red. So a dichromat probably could not easily distinguish chlorine gas from neon gas.
