hey all,

i would like to have ideas for making a color blind test image; especially multi colored, random circles.

blending and/or manual c&p would take so much time, so if any other pratical way would make my day. thanks in advance.

Didn't you just answer your own question with your attachment? That's pretty much the standard for colour blindness tests. Just re-create it with your own pattern in the middle.

i don't need it to be the same and not looking for a replication. i know the text can be anything depending on the colouring but, the thing is, i can't quite figure out the automation process of multiplying random shapes, like i don't want to hand-place say 60-70 circles.

hope i'm clearer.

It's that attitude that makes western society what it is today.

Why are you too bone idle to hand place seventy dots? Have you anything else to do?

I'm color blind Changing the hue I am able to read it, though.

can you code?

I've seen coders make interactive versions of this with Director.

I used to work with this guy, he made one. Although not on his site: i o t i c  e x p e r i m e n t s

maybe that kind of approach might work. thank you.

Create circles of different sizes, transform the whole batch to the left/right slightly and rotate, then "transform again" multiple times so that you have solid pile of circles to pick from, start clicking them and deleting... good/quick starting point?

So how does a NON-color-blind person make a color-blindness test? :shrug:

[d3n!s3_Ü]

I still have clear eyesight so yeah, I see it! :yes:

[Dusteh]

First thing I think of to do this is:

Joshua Davis | Studios » » random grid 01

I was wondering the same thing.

[steveb]

We shall probably never know.

(Are you two serious?!)

Anyhoo, the best and prettiest vision test I've taken part in involved 15 discs with pure cyan at one end and pure magenta at the other. The colours of the discs in between were sampled from the gradient from C to M and of course the idea is to get them in the right order.

A project to try out yourself at home on a rainy afternoon?

Is there site with a lot of color blind test?

[steveb]

Use the Google fer crisesakes!
Entering color blind test threw up this Ishihara Test for Color Blindness with a link to another interesting site/sight. Online color blindness tests aren't to be trusted because of monitor display errors but you can at least get some idea of the system. The more advanced Ishihara tests which you might be subjected to by an ophthalmologist (eye doctor) contain some tricks - for example, after a series of tests where numbers are displayed, suddenly there are also letters in the mix. What looks like 45 at first glance is in fact A5. (I could see it, the doctor couldn't!)
My color vision was tested very thoroughly when I worked at a tv station as a vision mixer. The doctor who tested me was suspicious because I was scoring 100% on all the tests and we ended up going through the ultra crafty obscure Ishihara tests too. The doctor said my color vision was phenomenal. I had that impression too - the folder containing the final tests was covered in a thick layer of dust and obviously hadn't been touched for years!

if you just type 'color blind test' on a search engine you get millions of results
(try searching for images)

I wish theyd use something cool like animal shapes instead of numbers. Although Im color blind (red green) I still see color but I cant see the number in that pic. So I wouldn't see the animal shapes anyway. but still.. why numbers? numbers suck.

Because numbers are objective. Say they used fruits.

Optometrist (O): "What can you see in this picture?"
Person (P): "Umm... a pear."
O: "Ok... what about this one?"
P: "A banana?"
O: "I think you may be red-green colour blind. The first object was an apple, and the second was a cucumber."

I believe I used Animals as an example. You sir need a snack.

I was responding to the "why numbers" question. But anyway :

O: "What can you see in this picture?"
P: "Umm... a mammoth"
O: "Ok... what about this one?"
P: "A parrot?"
O: "I think you may be red-green colour blind. The first object was an elephant, and the second was a budgerigar."
...

My point is that everyone who uses an alphabet with the modern Arabic numerals can recognise those symbols, while responses to other objects may be influenced by things like culture of preference.
