I received an email from Mr. Myrtone Bigpond:
„I don’t know whether you have noticed but I made another post clearing up a previous misunderstanding. As I understand it, you can distinguish red, yellow, green and blue but might have a green-turqoise confusion. It would be nice if you could be more specific about your colour vision anomaly, so that people like me can understand better about what you can see. I’ve heard that green weak people are often unaware of their colour-anomaly until they have their colour vision tested.
Here is my answer:
„Hello Myrtone,I will answer emails that show no condescending [tone]. I remember you were not willing to learn, but I am glad you changed your mind.I am green-weak, my vision anomaly is deutanomaly. Yes, I distinguish Red very well, I even like red. When looking from 5th floor at the road red cars are the most obvious to me.I can distinguish red, green, blue, all basic colours in fact (brown, pink etc). Sometimes I confuse mauve with blue. I deal best with colours of objects that reflect light. When they emit lights, such as car back lights, I cannot distinguish well between read and orange respectively orange and yellow. In fact I have problems naming colours of small emitting lights such as flying plane lights.I was unaware of my anomaly until I was 14 when I was tested with Ishihara plates. Nevertheless I was really bad at finding mushrooms (in the field, I am from the countryside) or red berries. The difference between the berry’s red and grass’s green was not as big for me as that perceived by normal colour vision, and as such these berries did not „jump in my view”: they were not obvious. Same for mushrooms that have colours similar to the soil.This anomaly of view did not block ladies in my family to ask me if they combined nice the garments they clothed with. They seem to appreciate my aesthetic sense.It is important to understand that most of the problems colorweaks (or colorblinds) have is due to a colour on a background,not the colour itself. The colour / background colour combination generates the confusion, and in reality these combinations are rare. Mr. Ishihara had to work a lot with his colourblind assistant to develop the colour scheme of his plates.Why do you need all this info?„
