Color blindness

[Zeevah]

My daughter is nearly three years old and has recently been diagnosed with a squint. We have an appointment with a pediatric ophthalmologist in two weeks’ time.

I’ve noticed that she consistently confuses blue and green, although she can identify other colors correctly. I’m concerned that this may indicate a degree of color vision deficiency. I will raise this at her upcoming appointment, but I wanted to ask if anyone else’s child has experienced difficulty distinguishing between blue and green at this age.

Thank you.

Where you draw the line between blue and green is a language thing. My 5 yo has a different definition to me and my partner. He has significant blindness so not a fair test. She has been tested for colour blindness and she's completely fine.

Have you shown her ishihara test cards? Can she read numbers? I don't what age they are used and likely only applicable used by a clinician, but you can view them online to test her to get an idea.

My eldest DD has blue green colour blindness diagnosed at 19, it’s very rare in girls.

Thank you so much for all your replies. She can match them correctly — for example, if you give her a crayon and ask her to match it, she’s able to do it. I know it’s not a big problem, but I’m still a little worried 😊

Hi Sorry to know about your daughters color blindness
Does she mix up between blue and green?
Or does she see them as gray.

sorry to ask this. Thanks 😊

Well we don’t know how she sees as it’s individual. If you Google you can look up how they think colour blind people see colour.

Green and blue are slightly different shades to her so wall climbing grips are difficult to tell apart. Van Gogh was blue green colour blind hence using such vibrant colours.

You didn't ask me this but my experience is similar to the poster you quoted:
There's a certain shade of blue that looks grey. Blue can also look purple and green. It depends on the shade

Colour blindness can be very varied from struggling to pick out similar colours to impacting day to day life.
My partner is very deficient in the ability to distinguish red /green and slightly deficient in blue /yellow. It causes a complete shift in how he perceives a lot of colours. Red and brown, blue and purple as well as the obvious. A lot of how he sees colours is how he thinks he sees colours and when something changes colour he doesn't see it..... For example when meat goes off and changes colour and he also can't see when meat is cooked as it still looks raw to him.

My brother is more colour blind than me, if that makes sense. He wanted to join the navy and comprehensively failed the colour blindness test. He’s a fabulous pen and ink / pencil artist but anything with colour looks quite trippy!
I’m ok with primary and secondary colours but tertiary colours confuse me. I was tested and for colour blindness and was on the “edge” of normal. This was donkey’s years ago! Things might have moved on!
I can’t choose my own foundation shade and I don’t “understand” the idea of a “cool blue”. I tend to go for monochromatic colour schemes for house decor and for clothes, I based all the colours around the main item. Blue and white striped top with red logo. Blue jeans, white socks, red shoes, blue bag. Can’t be doing with too many colours or patterns.

My brother has colour blindness but he mixes many more colours up than blue and green. Apart from his art paintings having been interesting 😂 I can honestly say it has never ever affected him in life and I didn't even notice until my mum told me about it.

Colour blindness is actually quite unusual in females.
It's about 1 in 10 males though and most of them get through life with very few issues.
Book her in for an eye examination this weekend and you can see!

It's around 1 in 200 females. I remember someone asking me about it as he wasn't aware it was a thing in females

I've met 2 males who are colourblind. One can only see in black, white and grey

Thanks a lot for all your replies. Will get her checked at the optician and see
thank you 😊

I think if she can match a crayon to a colour then she's probably fine, just naming her colours differently. Colour is both a cultural and an individual thing, particularly in the transitions between colours. Some languages don't differentiate between blue and green even today, others have different words for blue and light blue in the same way as we have different words for red and light red (pink). (I love colours and have a lot of colour conversations because I quilt and crochet, so I've done a bit of reading around it.)

I might also be that you are tetra chromatic, one in eight women (it's rare for men) have an extra cone in the eye. The extra cone is sensitive to yellow/orange light so people who have it can see a wider range of colours than regular three cone people. So you might be seeing things slightly differently to her even if she has normal vision.

Mine is colour blind and can’t distinguish between blue/ green. Tritanope, but I believe it’s more common in males, where the mother’s father is red green colour blind.
Mine also struggles particularly with yellow on a white background (can only see one colour) and is particularly confused with greens/ purples which appear the same shade.
green /blue can be a matter of language though.
Mine was fond of drawing traffic lights but the orange was usually pink and the green any shade of blue or purple, which is how we discovered it. Orangutans were described as ‘those giant pink monkeys’.

thanks for your reply
my daughter can identify all other colours properly
it is just green and blue. Even green is fine. It is the blue which she say green most of the time.

i hope it is just her language as she can match them properly

thanks all for your replies. Much appreciated
